An IC card includes a frame with a rectangular border open on one side, a printed circuit board equipping an electronic component, a plate-shaped connector, and one pair of conductive shell plates. The connector constitutes one side of the frame. The one pair of shell plates covers both faces of the frame and the connector. The connector has a housing, a plurality of male contacts arranged in parallel in the interior of the housing, and a short circuit terminal. The male contacts are such that one end portion is a connecting portion to an external terminal and another end portion is connected to the printed circuit board. The short circuit terminals are mounted on the housing such that one end portion is in contact with a predetermined male contact among the plurality of male contacts and another end portion is in contact with an inner wall of a shell plate.
