Abstract
A wiring assembly for equipment is produced at a low cost and has the same wiring connection as a flexible printed cable (FPC). Various kinds of terminal treatment processes are applied to the assembly. A circuit is formed by arranging polyurethane-insulated magnet wires 21 on a polyimide (PI) sheet 22 formed along a wiring circuit having bent, curved, and branched (jointed) portions. The formed circuit is coated with a PI sheet 23. Accordingly, an etching step such as in an FPC is not required. It is possible to produce a wiring assembly having the same function as an FPC at a low cost and to effect various kinds of terminal treatments as with an FPC. A wiring assembly having a single crossing in a circuit is formed by using insulated conductors.
