## Abstract

A flat routing material includes a flat conductive material and an insulating coating covering the conductive material. The routing material includes a bent portion as a part bending in an edgewise direction at a predetermined angle or more, and one or more folds extending toward the outer peripheral side of the bent portion are provided on at least the inner peripheral side of the bent portion. The folds are manufactured by press working.

## Claims

### Claim 1

A flat routing material comprising:
a flat conductive material; and
an insulating coating covering the conductive material, wherein:
the routing material includes a bent portion as a part bending to an edgewise direction at a predetermined angle or more; and
one or more folds extending toward an outer peripheral side of the bent portion are provided on at least an inner peripheral side of the bent portion.

### Claim 2 (depends on 1)

The routing material according to claim 1, wherein the conductive material has a uniform thickness.

### Claim 3 (depends on 1)

The routing material according to claim 1, wherein the conductive material is made of aluminum.

### Claim 4

A manufacturing method of a routing material, the manufacturing method comprising a step of bending, to an edgewise direction, a flat routing material including a flat conductive material and an insulating coating covering the conductive material, by pressing the routing material by a mold so as to form one or more folds on at least a first edge side of the routing material such that the one or more folds extend toward a second edge side of the routing material, wherein the routing material is bent such that the first edge side becomes an inner peripheral side of the routing material.

### Claim 5 (depends on 4)

The manufacturing method according to claim 4, wherein, in the step of bending the routing material, the conductive material has a uniform thickness.

### Claim 6 (depends on 4)

The manufacturing method according to claim 4, comprising a plurality of steps of bending the routing material, wherein each of the steps is performed by use of different molds such that a height of the folds is gradually increased, and a bending angle of the routing material is gradually increased.
