ABSTRACT:
A circuiting device comprising a flexible base member having end portions to be fixed, a movable portion therebetween and conductor patterns carried on the base member. Parts of the portions to be fixed adjacent to the movable portion are covered by protective films which prevent solder from flowing to the movable portion from the portions to be fixed. This arrangement prevents disconnection and short circuit in the conductor patterns on the circuiting device, and facilitates connecting operations.
