いる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIGS. 5 and 6, the casing 22 of the portable wireless device 21 is made of an insulating material such as plastic.
3, a cover main body 24, and a battery cover 26. A printed wiring board 26 is accommodated within the housing body 23. This printed wiring board 26 constitutes an electronic circuit, and also includes a battery holder part 27, a battery terminal (not shown), etc., and a battery (not shown) can be housed in the battery holder part 27. can. A recessed part 31 is formed on the inner surface of the wide side plate 30 on the side opposite to the open part 28 in the housing body 23, leaving a peripheral edge, and a recessed part 32 is formed on the outer surface of the side plate 3o, leaving a peripheral edge. Further, a recessed step portion 33 is formed on the outer periphery of the recessed portion 32. There are multiple locations (
In the illustrated example, holes 34, 35, and 36 are formed at three locations, and a hole 37 is formed at a position closer to the inner long side. The inner antenna plate 38 is made of a conductive material such as a metal plate, and is connected to the hole 3.
A hole 39 is formed corresponding to 7, and a contact Q is formed in an oblique direction by cutting and raising at an inward position in the width direction. The outer antenna plate 41 is made of a conductive material like the inner antenna plate 38, and contacts 42, 43, 44 are formed diagonally by cutting and bending corresponding to the holes 34, 35, 36. A contact 46 is formed in an oblique direction by cutting and bending corresponding to the hole 3A. This contact 46 is formed narrower than the hole 39. Therefore, the inner antenna plate 38
