There is a drawback that the sheet metal thickness of the element portion and the base plate portion occupies the inner dimension between them. Furthermore, a certain amount of space is also required between the element part and the inner surface of the rear case. Therefore, the built-in antenna occupies a large space, which has been a major obstacle in making portable wireless devices smaller and thinner.

FIG. 1 is a perspective view showing an exploded state of an embodiment of the present invention, and FIG. 2 is a sectional view of the embodiment. In FIG. 1, the body of the radio consists of a rear case 11 and a front cover 12, both of which are made of an insulating material such as plastic. A part of the inner surface of the rear case 11 (the shaded area 11A in FIG. 1) has a conductive treatment part 11A such as plating or conductive coating to make it conductive. Further, a part of the printed wiring board 13 (the shaded area 13A in FIG. 1) has a conductive ground pattern processing section 13A. Here, the conductive treatment section 11A on the inner surface of the rear case 11 and the ground pattern treatment section 13A on the printed wiring board 13 face each other as shown in FIG. 2 in the assembled state, so that they have a parallel positional relationship. Fix it. Therefore, a part 11A of the inner surface of the rear case 11 is an element part and a part 1 of the printed wiring board.
3A becomes the ground plate part, forming exactly the inverted F-shaped built-in antenna. At this time, the power supply section 14 and the short bar 15 are fixed in advance to the ground pattern processing section 13A of the printed wiring board 13 by soldering or the like, and the tip part has a spring property. to form a built-in antenna.
