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.
