## Abstract

It is an object of the present invention to provide a technology with which a protective portion with high protective capabilities is provided while avoiding an operation to switch out binding adhesive tape much as possible. A wire harness includes: a wire; and a tape-wrapping protective portion provided in at least a partial region along a longitudinal direction of the wire, the tape-wrapping protective portion including a spiral-wrapping portion in which an adhesive tape is wrapped in a spiral shape around the wire, and in the portion where the spiral-wrapping portion is provided, the adhesive tape being wrapped so as to form more than two layers.

## Claims

### Claim 1

A wire harness comprising:
a wire; and
a tape-wrapping protective portion provided in at least a partial region along a longitudinal direction of the wire,
wherein the tape-wrapping protective portion includes a spiral-wrapping portion in which an adhesive tape is wrapped in a spiral shape around the wire,
in the portion where the spiral-wrapping portion is provided, the adhesive tape is wrapped so as to form more than two layers,
the tape-wrapping protective portion includes a first tape-wrapping protective portion, and
the spiral-wrapping portion of the first tape-wrapping protective portion is an overlap wrapping portion in which the adhesive tape is wrapped so that a region greater than half of the width thereof is sequentially overlapped.

### Claim 2 (depends on 1)

The wire harness according to claim 1,
wherein the first tape-wrapping protective portion further includes an end portion wrapping portion that is provided at one end portion of the first tape-wrapping protective portion along the longitudinal direction of the wire,
in the end portion wrapping portion, adhesive tape is wrapped to form a plurality of layers at the same position, and
a wrap-start portion of the overlap wrapping portion overlaps the outer circumferential side of the end portion wrapping portion.

### Claim 3 (depends on 2)

The wire harness according to claim 2, further comprising
a connector provided at an end portion of the wire,
wherein the end portion wrapping portion is provided in the first-wrapping protective portion so as to be located nearest the connector in the longitudinal direction of the wire.

### Claim 4

A wire harness comprising:
a wire; and
a tape-wrapping protective portion provided in at least a partial region along a longitudinal direction of the wire,
wherein the tape-wrapping protective portion includes a spiral-wrapping portion in which an adhesive tape is wrapped in a spiral shape around the wire,
in the portion where the spiral-wrapping portion is provided, the adhesive tape is wrapped so as to form more than two layers,
the tape-wrapping protective portion includes a second tape-wrapping protective portion, and
a plurality of layers of the spiral-wrapping portion of the second tape-wrapping protective portion overlap.

### Claim 5 (depends on 4)

The wire harness according to claim 4,
wherein the spiral-wrapping portion of each layer in the second tape-wrapping protective portion is wrapped in a spiral shape so that laps of the adhesive tape do not overlap.
