Abstract:
A method of manufacturing a flat cable having a length and a width, the flat cable comprising first and second insulator sheets, and at least one adhesive layer interposed therebetween, the flat cable further comprising a plurality of conductor elements arranged in parallel relation to one another over the length of the first and second insulator sheets, said method comprising:providing said adhesive layer on at least said first insulator sheet so as to face said second insulator sheet; interposing said conductor elements between said adhesive layer and said second insulator sheets; provisionally adhering said first and second insulator sheets including said conductor elements through said adhesive layer by a heat pressing force exerted from outside said first and second insulator sheets; and bonding, by ultrasonic welding, said first and second insulator sheets through the zones extending along said length thereof and located outside the loci where said conductor elements are arranged.
