A guiding function of an annular contact upon mating / removal with / from an opposing connector can be maintained well with a simple configuration. An annular contact is formed with an unruptured annular member having no ruptured part in a circumferential direction and continued in the circumferential direction. As a result, compared with a conventional annular contact having ruptured parts in the circumferential direction, rigidity is increased while maintaining necessary elasticity; and, for example even when an opposing connector is mated or removed in a direction inclined in an axial direction with respect to the axial direction of the annular shape, conventional twisting deformation is suppressed in the annular contact, and the opposing connector is stably guided along the axial direction of the annular shape, thereby well maintaining a mating guiding function of the annular contact.
