## Abstract

A heat-resistant and oil-resistant insulated electric wire is mounted on a vehicle, and includes a conductor portion and an insulator covering a periphery of the conductor portion. The insulator is made of polyphenylene sulfide resin. The conductor portion includes a twisted wire formed by twisting a plurality of element wires. At least a part of the plurality of element wires includes a plated fiber. The plated fiber is formed of a high-strength fiber and metal plating surrounding a periphery of the high-strength fiber.

## Claims

### Claim 1

A heat-resistant and oil-resistant insulated electric wire mounted on a vehicle, comprising:
a conductor portion; and
an insulator covering a periphery of the conductor portion,
wherein the insulator is made of polyphenylene sulfide resin,
wherein the conductor portion comprises a twisted wire formed by twisting a plurality of element wires, and
wherein at least a part of the plurality of element wires is a plated fiber formed of a high-strength fiber and metal plating surrounding a periphery of the high-strength fiber.

### Claim 2 (depends on 1)

The heat-resistant and oil-resistant insulated electric wire according to claim 1,
wherein a part of the plurality of element wires comprises the plated fiber, and
wherein a remainder of the plurality of element wires comprises a metal wire consisting essentially of one or more kinds of metals and having a conductivity higher than that of the plated fiber.

### Claim 3 (depends on 2)

The heat-resistant and oil-resistant insulated electric wire according to claim 2,
wherein the plated fiber is provided on an inner layer side of the conductor portion, and
wherein the metal wire is provided on an outer layer side of the conductor portion so as to surround a periphery of the plated fiber.
