Connector

A connector includes: a cylindrical terminal electrically connected to a cylindrical mating terminal; an internal terminal located in the cylindrical terminal; and a housing which holds the cylindrical terminal. The cylindrical terminal has a contact portion configured by bending a conductor having a plate shape into a cylindrical shape so that one edge portion of the conductor is in contact with the opposite other edge portion of the conductor. The one edge portion has a concave shape at a circumferential end portion thereof in which a thickness of the one edge portion is reduced outward in a radial direction of the cylindrical terminal to form a reduced-thickness portion. The other edge portion has a concave shape at its circumferential end by reducing the thickness of the further edge portion radially inward to form an opposite further reduced thickness portion. The contact portion is configured by overlapping the one reduced-thickness portion and the other reduced-thickness portion. 一种连接器，包括：圆筒状端子，其与圆筒状配对
