Abstract

The present invention relates to a high-frequency circuit device provided with a shield plate structure. A printed circuit board (12) and a shield plate structure (13) are accommodated within a casing (11) of such a device. The shield plate structure (13) is formed of a single plate which is punched into a specific shape and bent to form the shield plate structure, which shields the various circuit sections (15a, 15b, etc). The shield plate has leaf-like parts (18) which are connected to a main part (19). <IMAGE>
