Abstract

A wire harness having a shield structure that can exhibit a required shield effect and sufficiently meet demands for cost mitigation and weight reduction is provided. The wire harness is provided with an electrical line group that is held in a bundled manner, in which at least a portion of electrical lines that are positioned on the outer circumferential side of the electrical line group each have a metal thin-film for shielding as the outermost layer, the metal thin-film being formed so as to attach to an outer circumferential surface portion of a sheathing that surrounds a conductor of the electrical line, and a drain wire or another ground connection member that is grounded and comes into contact with the metal thin-films of the electrical lines.

First claim

What is claimed is:

1. A wire harness comprising:
an electrical line group that is held in a bundle, in which at least a portion of electrical lines that are positioned on an outer circumferential side of the electrical line group each have a metal thin-film for shielding as an outermost layer, the metal thin-film being formed so as to attach to an outer circumferential surface portion of a sheathing that surrounds a conductor of an electrical line;
a ground connection member that is grounded and comes into contact with the metal thin-films of the at least a portion of the electrical lines;
a holding member that holds the plurality of the electrical lines in the bundle; and
the ground connection member positioned between and contacting an outer circumference of the electrical line group and the holding member.

2. The wire harness according to claim 1 , wherein the metal thin-films of the at least a portion of the electrical lines are each a vapor deposition film formed by RF ion plating.

3. The wire harness according to claim 1 ,
wherein the holding member includes a holding member body that holds the plurality of the electrical lines in the bundle and a connection conductor film that is formed so as to attach to the holding member body, and
the connection conductor film includes a vapor deposition film that is formed by RF ion plating.

4. The wire harness according to claim 2 ,
wherein the holding member includes a holding member body that holds the plurality of the electrical lines in the bundle and a connection conductor film that is formed so as to attach to the holding member body, and
the connection conductor film includes a vapor deposition film that is formed by RF ion plating.
