## Abstract

A coil wire for a rotating electric machine includes: an element wire assembly formed by bundling a plurality of element wires, the plurality of element wires being coated so as to be insulated from each other; and a coating member having conductivity, the coating member coating a periphery of the element wire assembly, the coating member being positioned in a slot of a stator of the rotating electric machine and being obliquely wound with respect to a longitudinal direction of the coil wire, and the coating member being formed with a plurality of conductive belts electrically insulated from each other.

## Claims

### Claim 1

A coil wire for a rotating electric machine, comprising:
an element wire assembly formed by bundling a plurality of element wires, the plurality of element wires being coated so as to be insulated from each other; and
a coating member having conductivity, the coating member coating a periphery of the element wire assembly, the coating member being positioned in a slot of a stator of the rotating electric machine and obliquely wound with respect to a longitudinal direction of the coil wire, and the coating member being formed with a plurality of conductive belts electrically insulated from each other.

### Claim 2 (depends on 1)

The coil wire for a rotating electric machine according to claim 1, wherein the plurality of conductive belts are wound in parallel via an insulating member disposed between each other.

### Claim 3 (depends on 1)

The coil wire for a rotating electric machine according to claim 1, wherein the plurality of conductive belts are wound in parallel at an interval from each other.

### Claim 4 (depends on 1)

The coil wire for a rotating electric machine according to claim 1, wherein the coil wire is a generally U-shaped conductor segment that has two legs and a connection section connecting one ends of the legs together, the connection section and distal end sections of the legs of the conductor segment constitute coil end sections, and an intermediate section of the leg that is positioned in the slot forms a slot-surrounded section.

### Claim 5

A coil body for a rotating electric machine, comprising
a coil wire for a rotating electric machine, including:
an element wire assembly formed by bundling a plurality of element wires, the plurality of element wires being coated so as to be insulated from each other; and
a coating member having conductivity, the coating member coating a periphery of the element wire assembly, the coating member being positioned in a slot of a stator of the rotating electric machine and being obliquely wound with respect to a longitudinal direction of the coil wire, and the coating member being formed with a plurality of conductive belts electrically insulated from each other,
wherein the coil wire for the rotating electric machine is formed in a coil shape so as to be wound around a tooth of a stator of the rotating electric machine.
