PROBLEM TO BE SOLVED: To provide a folding portable wireless unit in which high antenna performance is secured at a telephone call state, without projection of an antenna and design nature is enhanced at a state that a case is closed. SOLUTION: The folding portable wireless unit is constituted by structure that an upper case 2 and a lower case 7 are connected by a first hinge part 6 and the lower case 7 and an opening/closing cabinet 10 are connected by a second hinge part 8 and output of a radio circuit 13 on a circuit board 17 arranged inside the lower case 7 is electrically connected with a second rotational axis 9 by spring contact and soldering via a matching circuit 14. A conductor element 11 is constituted of sheet metal molded in the L-shape with its length Le of approximately quarter wavelength (for example, about 37mm in a 2GHz band). One end of the conductor element 11 is connected with the second rotational axis, for example, by the spring contact and the soldering and the other end is opened. In addition, the conductor element 11 is arranged in parallel with the width direction of the folding portable wireless unit. COPYRIGHT: (C)2006,JPO&NCIPI
