The plurality of contact claws are arranged at intervals in a circumferential direction of the memory contact section, and the plurality of contact claws are capable of radially contracting. The terminal having memory function can realize a butting without an insertion force, and ensure a contact area and a contact force between a terminal and a mating terminal by a temperature rise during working, and improve contact reliability. Since the insertion force is not required, the work is easier and the working efficiency is improved.
