A first conductive pattern is printed on a first insulating film and includes a transmitting antenna, a receiving antenna, an inductor section, and a diode connected in parallel with the inductor section. The inductor and parallelly-connected diode form an LC resonator of the first conductive pattern. A second insulating film, having first and second through-holes for exposing two end portions of the inductor section, is fixedly attached to the first insulating film and a third insulating film and is used as a spacer between them. A second conductive pattern is printed on the third insulating film spanning the first second through-holes, and a conductive member housed in the first through hole joins the first and second conductive patterns. A semiconductor chip of a Schottky diode is used as the diode and housed in the second through-hole in direct contact with the first and second conductive patterns.
