There are provided a conductor for busbar electric wire, and a busbar electric wire configured by a conductive plate material having a substantially rectangular cross-sectional shape, the conductor including: an opening formed on one side in a width direction orthogonal to a longitudinal direction of the plate material, the width direction corresponding to a planar direction of the plate material.

A conductive structure includes: a single-layer busbar that is formed in a plate shape and constitutes a conductive path; and a multi-layer busbar that is configured by laminating a plurality of busbars which are formed as plates thinner than the single-layer busbar and that is joined to an end of the single-layer busbar and constitutes the conductive path. The multi-layer busbar includes a main body portion in which at least some of the laminated plurality of busbars are capable of mutual displacement relative to the busbars adjacent thereto, and a joining end located at a end of the main body portion on the single-layer busbar side and in which the laminated plurality of busbars are incapable of mutual displacement relative to each other, the joining end being joined to the end of the single-layer busbar.

A cable includes: a conductor including strands densely arranged, the strands including out most strands located at outermost parts of the conductor and inner side strand located on inner side of the outermost strands; and an insulation covering that covers the periphery of the conductor. The insulation covering is in surface contact with the outermost strands, and is provided in a manner such that gaps are provided between the insulation covering and the inner side strands. In the method for manufacturing the cable, a fluid resin having a viscosity of greater than or equal to 323.6 Pa.Math.sec at the point of extrusion is used, and the extrusion pressure of the resin is adjusted in a manner such that the insulation covering is in surface contact with the outermost strands and such that gaps are provided between the insulation covering and the inner side strands.

A flat routing material includes a flat conductive material and an insulating coating covering the conductive material. The routing material includes a bent portion as a part bending in an edgewise direction at a predetermined angle or more, and one or more folds extending toward the outer peripheral side of the bent portion are provided on at least the inner peripheral side of the bent portion. The folds are manufactured by press working.

The present disclosure provides a bend-resistant wire, a preparation method therefor and a flexible display panel, and relates to the field of display technologies. The bend-resistant wire is formed on a side surface of a flexible substrate of a flexible display panel that is located in a fan-out region, the bend-resistant wire includes a conductive layer, the conductive layer has hollow parts formed corresponding to a bent region of the flexible substrate, and an area of each of the hollow parts in the bent region is positively correlated with a curvature of the corresponding bent region. An objective of the present disclosure is to provide the bend-resistant wire, the preparation method therefor and the flexible display panel, which can reduce a risk that a fan-out wire of the flexible display panel breaks when the flexible display panel is bent.
