The contact unit (CU) is made of a linking portion (23), intermediate portions (24) that extend from both ends of the linking portion (23) towards an aperture side of the plug insertion hole (H), and folded portions (25) that are folded over from the ends of the intermediate portions (24) to the inner end side of the plug insertion hole (H), projecting into the plug insertion hole (H), the contact unit being formed in one piece by bending a band-shaped conductor, such as a copper alloy, and the tip contacts (CT) being formed on a free end side of the folded portions (25).
