造工程の高速化に役立つなどの利点を有する。According to the present invention, since the slot of the wire pressure contact portion provided in the circuit conductor and the wire holding groove of the elastic body of the wire holding portion are provided so as to coincide with each other, the wire pressed into the slot is connected to the wire. It can be held elastically by being sandwiched by the holding groove, and the tension applied to the wire at the time of wiring is relaxed without directly acting on the pressure contact part, preventing the pressure contacted wire from falling out of the slot, breaking, cutting, etc. Reliability and adaptability to automated manufacturing processes is significantly improved. In addition, there is no need for a holding component to be attached to the press contact portion, which is advantageous in that it helps to reduce the weight and speed up the manufacturing process.
