Abstract: A conductive metal frame attached to an upper case is electrically connected to hinge metal member. The hinge metal member is connected to a hinge metal member by a rotary shaft in a rotatable manner. The hinge metal member, a further hinge metal member, and the rotary shaft are made of conductive metal so that electric continuity is obtained at contact points thereamong. The further hinge metal member is connected to a matching circuit on a circuit board via a feedpoint terminal. A conductor element is connected to a ground pattern of the circuit board at a position close to a point at which the matching circuit is grounded. The structure as described above provides a folding portable wireless unit that can secure a high antenna performance in a calling state and a waiting state.

Abstract: A folding type mobile radio that can ensure high antenna performance on a desk in addition to realizing of downsizing and slimming down is provided. An antenna element 9 has a main part placed in a lower case 10 roughly in parallel with the cabinet width direction and is connected to a matching circuit 13 on a circuit board 11 placed in the lower case 10 by spring contact or soldering, for example. The matching circuit 13 is connected to a wireless circuit 14. A conductor element 3 is placed in an upper case 1 and is connected at one end to a ground pattern of an upper circuit board 2 and is opened at an opposite end. Particularly, the conductor element 3 has a main part placed roughly in parallel with the antenna element 9 and the connection part with the ground pattern of the upper circuit board 2 is placed on the antenna element feeding part side on the hinge part 5 side.
