Abstract

A shielded electric wire includes an electric wire including a conductor portion and a cover portion covering the conductor portion, a shielded braid formed of a conductive linear material, the shielded braid covering an outer periphery of the cover portion and a sheath formed of an insulating resin, the sheath being provided around the shielded braid. The electric wire and the shielded braid together form an electric wire assembly. A flexible value of the sheath is equal to or smaller than a flexible value of the electric wire assembly, the flexible value being a value of a load required for bending an object for a predetermined extent.

First claim

What is claimed is:

1. A shielded electric wire comprising:
an electric wire including a conductor portion and a cover portion covering the conductor portion;
a shielded braid formed of a conductive linear material, the shielded braid covering an outer periphery of the cover portion; and
a sheath formed of an insulating resin, the sheath being provided around the shielded braid,
wherein the electric wire and the shielded braid together form an electric wire assembly,
wherein a flexible value of the sheath is equal to or smaller than a flexible value of the electric wire assembly, the flexible value being a value of a load required for bending an object for a predetermined extent, and
wherein, when an environmental temperature is 25° C., an occupancy rate is equal to or less than 45% and equal to or greater than 15%, the occupancy rate being a value obtained by dividing a sum of a cross-sectional area of the electric wire and a cross-sectional area of the shielded braid by an area of a circle whose diameter being an inner diameter of the sheath.

2. The shielded electric wire according to claim 1 ,
wherein the occupancy rate is equal to or greater than 30%.

3. A wire harness comprising:
the shielded electric wire according to claim 1 .
