A rear case and a front case are unified to form a casing. An internal
antenna is accommodated in a predetermined space in the rear case, and
supported in a state that it is inserted between the rear case and a
printed circuit board. An output end of an antenna metal element is
connected with a feeding point of the internal antenna, and an input end
thereof is connected with a feeding terminal of the printed circuit board
via a contacting means. Accordingly, there is no necessity for soldering
the antenna metal element to the feeding terminal of the printed circuit
board, the number of structural elements can be reduced, and the
fabricating process can be simplified.
