Abstract

PROBLEM TO BE SOLVED: To prevent a cable body from being deteriorated or ruptured by stress concentration without increasing the number of components used, restrictions on wiring, and manhours for mounting, with a simple structure. SOLUTION: A cable body 14 is structured by disposing plural conductors 17 between insulating material sheets 16, 16, and it has, at its both end parts, a connector connecting part 18 where the conductors 17 are exposed. A reinforcing plate 15 is additionally provided on the surface opposite to the connector connecting part 18 by adhesion for instance. The end part of the reinforcing plate 15 is formed into a knurled shape (a mark 19 is put on the knurled part).
