ABSTRACT:
A mobile cellular telephone 10 has a case 11 which is formed of frame portions 11a through 11f made of, for example, a reinforced plastic, a non-directional chip antenna 12, a circuit board 13 having the chip antenna 12 on one major surface (first major surface) 13a, and a copper-made reflective plate 14, which serves as means for attenuating a transmission output of the chip antenna 12. The reflecting plate 14 is provided between the circuit board 13 and the frame portion 14e in such a manner that it faces the first major surface 13a of the circuit board 13 with an intervening gap. Also, the reflecting plate 14 is connected to the ground pattern 19.
