## Abstract

A wire harness includes a first conductor path having a high priority in protection, a second conductor path having a priority in protection which is lower than that of the first conductor path, and an external member having a tubular shape and accommodating the first conductor path and the second conductor path altogether so as to protect them. The external member has a form in which the first conductor path is positioned farther away from a road surface than the second conductor path within a predetermined range in a longitudinal direction thereof.

## Claims

### Claim 1

A wire harness comprising:
a first conductor path having a high priority in protection;
a second conductor path having a priority in protection which is lower than that of the first conductor path; and
an external member having a tubular shape and accommodating the first conductor path and the second conductor path altogether so as to protect them,
wherein the external member has a form in which the first conductor path is positioned farther away from a road surface than the second conductor path within a predetermined range in a longitudinal direction thereof, and
wherein the external member has a ceiling wall, a bottom wall, a left wall, and a right wall, in which the ceiling wall has a larger radius of curvature than the bottom wall.

### Claim 2 (depends on 1)

The wire harness according to claim 1, wherein a portion of the wire harness corresponding to the predetermined range of the external member is formed according to a routing length on an underside of a vehicle floor.

### Claim 3 (depends on 1)

The wire harness according to claim 1, wherein a voltage value of the first conductor path is higher than that of the second conductor path.

### Claim 4 (depends on 1)

The wire harness according to claim 1, wherein the first conductor path includes two conductor paths and the second conductor path includes one conductor path.

### Claim 5 (depends on 1)

The wire harness according to claim 1, wherein the first conductor path includes three conductor paths and the second conductor path includes two conductor paths.

### Claim 6 (depends on 5)

The wire harness according to claim 5, wherein the three conductor paths of the first conductor path are aligned laterally side by side.

### Claim 7 (depends on 1)

The wire harness according to claim 1, wherein upon an event that a vehicle rides on a curb or in an event that a foreign matter comes to collide with the wire harness from a road surface side, the second conductor path having the lower priority in protection is affected before the first conductor path having the high priority in protection is affected.

### Claim 8 (depends on 7)

The wire harness according to claim 7, wherein the second conductor path functions as it were a shield for the first conductor path, and when the second conductor path is subjected to impact, the impact so received is absorbed and dispersed by the second conductor path.
