A chip-type antenna (2) and a snaked, band-shaped conductor (7) as a pair of radiation elements fed at the center, a circuit unit (3) havingatransmission/receptioncircuitthatisconnected to respective feeder lines (8, 9) for the radiation elements, and a connector (4) that connects, to an external circuit, lead lines leading from the circuit unit are arranged on an insulative substrate to be mounted on a mother board. The pair of radiation elements extend along two adjoining sides of the insulative substrate so as to generally assume an L-shape in a plan view. <IMAGE>
