A flexible flat cable manufacturing system comprises a tape conveying device conveying an adhesive tape along a first direction, and a wire conveying device conveying a row of wires along a second direction perpendicular to the first direction and parallel to a width direction of the conveyed adhesive tape. A wire pressing device presses and pastes the part of the row of wires facing the adhesive tape onto the adhesive tape. A wire cutting device cuts the row of wires to obtain a row of wire segments pasted on the adhesive tape and separated from the row of wires and produces a flexible flat cable including the adhesive tape and the wire segments pasted on the adhesive tape.

A wiring member-equipped adherend includes: a wiring member including a sheet and a wire-like transmission member fixed to the sheet; an adherend provided in a position where the wiring member is disposed in a vehicle and fixed to the sheet via a first fixing member; and a cover covering the wire-like transmission member from a side opposite to the sheet. The cover is fixed to the adherend via a second fixing member on at least one side of the wiring member.

The present invention has the following configuration. The present invention relates to a low-loss flat cable signal line for an ultra-high frequency, wherein the signal line plated, by a manufacturing method using an electroplating bath, on a micro circuit pattern part formed in a cylindrical circuit mold configured in the electroplating bath is configured to have an arc-shaped cross section or oval-shaped cross section, and a ratio (=a/b) between an electroplated line width (b) and a micro circuit pattern part line width (a) is 0.3 or less.

A wiring member includes: a wiring body including a plurality of wire-like transmission members, a first sheet to which the plurality of wire-like transmission members are fixed, and a second sheet to which at least some of the plurality of wire-like transmission members are fixed; and a connector provided to end portions of the plurality of wire-like transmission members. The second sheet is provided between the first sheet and the connector. Two or more wire-like transmission members including all of thinnest wire-like transmission members in the plurality of wire-like transmission members are fixed to the second sheet.

A wiring component includes a first wiring portion including a plurality of wirings arranged side by side in a first direction, a second wiring portion including a plurality of wirings arranged side by side in a second direction, and a coupling portion configured to couple the first wiring portion and the second wiring portion to each other, wherein an angle formed by the first direction and the second direction is changeable by deformation of the coupling portion.

High-frequency signal transmission cable includes: a dielectric layer; and first and second wiring layers arranged to sandwich the dielectric layer. The first wiring layer includes at least M (M indicating a natural number of 2 or more) differential transmission lines. The first wiring layer further includes a group of first ground lines including at least 2M first ground lines. The second wiring layer includes a group of second ground lines including at least M second ground lines. The group of first ground lines are allocated to the M differential transmission lines in accordance with a condition of at least two first ground lines per one differential transmission line in non-overlap manner, and the group of second ground lines are allocated to the M differential transmission lines in accordance with a condition of at least one second ground line per one differential transmission line in non-overlap manner. Each of the differential transmission lines is interposed between the at least two first ground lines and is opposed to the at least one second ground line.

A connection module includes: an electrical apparatus; and a wiring member including a connector connected to the electrical apparatus and a plurality of electrical wires extending from the connector in a state of being arranged in a width direction of the connector, wherein the plurality of electrical wires include a narrow width section in which the plurality of electrical wires are located to have a narrower width than a width of the connector in a section away from the connector and a tapered width section in which the plurality of electrical wires are located to have gradually a narrower width toward the narrow width section between the connector and the narrow width section, and the plurality of electrical wires extend from the connector and are folded back so that at least a part of the tapered width section is overlapped with the electrical apparatus.

A flexible flat cable according to an embodiment includes at least one bent portion including a first portion and a second portion provided to face the first portion, and a contact portion configured to bring the first portion and the second portion into close contact with each other.
