In a connector, to which a module body is electrically connected, a connector body has an inner side face defining a chamber which accommodates the module body. The chamber is formed with an opening from which the module body is inserted. A first, conductive terminal is provided on the inner side face such that a conductive member formed on an outer periphery of the module body is brought into contact with the first terminal in a case where the module body is plenarily accommodated in the chamber. A second, grounding terminal is provided on the inner side face and operable to be brought into contact with the conductive member of the module body.
