部材コストが高い、という問題点があった。The lubricous sliding member 40 is made of a resin such as polytetraflucaroethylene (PTFE), high density polyethylene, nylon, etc., which has a low frictional resistance and is formed into a flat strip or thread like the strip conductor 36. is there. However, when sandwiching the lubricative sliding material 40 between the insulating films 37 and 38, it is difficult to secure the adhesive strength,
There was a problem that the material cost was high.

音を抑えることができる。According to the method of manufacturing a flat cable of the present invention , the insulating resin sheet itself is subjected to a special process only by providing the insulating resin sheet with a wide portion on the side edge and folding the wide portion by folding means. Since it is not necessary, the manufacturing cost of the flat cable can be reduced. Further, since the side edges of the flat cable are smooth, it is possible to suppress the friction noise generated by sharply cutting the side edges of the conventional flat cable.

Moreover, the friction resistance can be further reduced by using Teflon or the like for the insulating resin sheet.
