An upper case ( 1 ) is connected to a lower case ( 2 ) in a hinge portion ( 3 ) so as to freely rotate. A plate shaped conductor ( 4 ) and a plate shaped conductor ( 5 ) are disposed along the surface of the case in the upper case ( 1 ). A ground plate ( 6 ) is formed in a ground pattern of a circuit board disposed in the lower case ( 2 ). The plate shaped conductor ( 4 ) and the plate shaped conductor ( 5 ) are selected by a high frequency switch ( 14 ) and connected to one end of a feeding portion ( 15 ). The other end of the feeding portion ( 15 ) is connected to the ground plate ( 6 ) to form a dipole antenna.
