A flat shielded cable includes conductors arranged in parallel, an insulating jacket section that covers the conductors and has an exposed conductor section which exposes a part of at least one of the conductors, and a shielding member that covers the jacket section. The conductor is electrically connected to the shielding member via the exposed conductor section. The shielding member has a first layer made of shielding material and a second layer made of binder resin containing metal filler. A D90 particle diameter of the metal filler is 6 m and a difference between a D10 particle diameter and a D95 particle diameter of the metal filler is 6 m or more, and the metal filler is contained in the second layer in an amount of 65 wt % or more.

Provided is a wire harness sheet by which it is possible to manually fix an electric wire bundle at an exact position without bending the electric wire bundle. A wire harness sheet 11 includes a sheet base material 13 that has a rectangular shape formed by a pair of first side portion 19 and a second side portion 21 in parallel with each other and by a third side portion 23 and a fourth side portion 25 orthogonal to the first side portion 19 and the second side portion 21; an adhesive layer 15 that is provided on one surface of the sheet base material 13; and a slit 17 which is cut into the sheet base material 13 in such a manner that the slit is formed along and in parallel with each the third side portion 23 and the fourth side portion 25 between each the first side portion 19 and the second side portion 21, and a placement region 31 of an electric wire bundle 27.

A shielded electric wire includes an electric wire; a shielding member that forms a shielding layer by covering a periphery of the electric wire; a sheet-shaped member that covers a periphery of the shielding member; and a protective member spirally wound on a periphery of the sheet-shaped member. The sheet-shaped member includes a first sheet material and a second sheet material. One surface of the first and second sheet materials is formed with an adhesive layer. The first and second sheet materials have a width longer than a half circumferential distance of the shielding member provided on the periphery of the electric wire, and are stuck on the shielding member to sandwich the shielding member. The adhesive layers of the first and second sheet materials are opposingly stuck in extra length portions protruding the shielding member in a width direction.

A sheathing member mounting apparatus is provided with a support mechanism that supports a sheet member from the side of a protective layer, electric wire holding mechanisms that hold an electric wire portion in a state of being disposed along a bonding layer of the sheet member, and a folding mechanism that folds the sheet member in two. A second region supported by a second support portion is pivoted toward a first support portion, whereby the electric wire portion of a wire harness is sandwiched in the folded sheet member to be covered.
