## Abstract

A method of fixing a flexible electrical conductor, in which a plurality of flat conductors in which their connecting ends to be connected to another circuit are exposed are integrally covered with a resin-made cladding member, to a fixing portion for connection to the other circuit, comprises the steps of: placing the cladding member on this side of the connecting ends on the fixing portion; and welding together the cladding member on this side of the connecting ends and the fixing portion so as to fix the flexible electrical conductor to the fixing portion. As a result, even if an external force is applied to the flexible electrical conductor, the force is not applied directly to a connecting portion for connecting the connecting ends to connecting ends of the other circuit, thereby improving the electrical reliability in the connection.

## Claims

### Claim 1

A fixing structure comprising:
a flexible electrical conductor having a plurality of flat conductors integrally covered with a resin-made cladding member and also having connecting ends that are connectable to another circuit and at which said plurality of flat conductors are exposed; and
a fixing portion for connection to said another circuit, wherein a portion of said cladding member that is between the plurality of flat conductors is welded to said fixing portion and wherein an irregular surface portion is provided on said fixing portion.
