PROBLEM TO BE SOLVED: To favorably meet the requirement for having multifunction. SOLUTION: This plug has a counterpart housing 110 to which a cylindrical counterpart projection 111 is installed, inner circumferential contact 130 which has been formed in a pin form, and counterpart outer circumferential contacts 140A, 140B, 140C fixed to the counterpart housing 110. The counterpart outer circumferential contacts 140A, 140B, 140C have contact parts 145A, 145B, 145C, and the contact parts 145A, 145B, 145C are arranged in parallel with the inner circumferential face of counterpart projection 111 mutually. Thus the plug is made to favorably meet the requirement for having multifunction.
