To simplify the connection of an antenna and to reduce the number of required parts by providing a cover for the connection between the antenna and the circuit unit so as to electrically couple the antenna to the circuit unit.
An antenna 1 is fixed on a device cover 4 in contact with a ground area 3. The antenna 1 has a spring pin 5 in contact with a radiation area 2. A circuit board 6 having a power feeding pad 7 and a lower cover member 8 exists under the antenna 1. When carrying the antenna 1 and the circuit unit together, the device cover 4 engages the lower cover member 8, holds the antenna 1 on the circuit board 6 and performs ground connection between the circuit board 6 and the antenna 1. At the same time, the spring pin 5 is compressed between the antenna 1 and the power feeding pad 7 and the connection of power supply to the antenna 1 is performed. The device cover 4 and the lower cover member 8 function as the shield of electronic parts 9 included in them.
