PROBLEM TO BE SOLVED: To securely prevent wrong insertion of a board with a structure being simplified. SOLUTION: In a shield mechanism of an electronic device, a board, on which a high-frequency circuit block is mounted, is contained in a conductive case and shielded thereby; wherein the board 1 has a cutout 1a, and the conductive case 2 has a rise tab 2b in correspondence with the cutout. Thus, wrong insertion, that is, mistaken insertion direction of the board is eliminated. Moreover, insertion operation of the board is easily carried out, consequently productivity is improved. A useless space on the board is removed, thereby high density mounting is realized, and consequently a sufficient shielding effect is obtained over the entire board. COPYRIGHT: (C)2006,JPO&NCIPI
