The IC chip includes a double voltage rectifier circuit to rectify an alternating voltage induced between the front surface and the rear surface of the IC chip. The second conductor functions as an antenna and also includes a slit extending from a center portion thereof in a longitudinal direction. The first conductor electrically connects both sides of the slit via the front surface and the rear surface of the IC chip.
