<p>PURPOSE:To enhance rigidity and to improve resistance of a memory card, an IC card against external noise of static electricity, magnetism, etc., by forming a frame of metal. CONSTITUTION:A frame 11 is formed with a hollow part in which a printed board 2 and a battery holder 5 are mounted and with an opening in which a connector 4 is mounted, and integrally formed by aluminum die casting using aluminum alloy, etc. Recesses to be adhered with metal panels 6 are formed on both front and rear surfaces of the frame 11. When the panels 6 are adhered in the recesses through adhesive sheets V, the side faces of the panels 6 are brought into contact with the sidewalls of the recesses. That is, the panels 6 are brought into contact with the frames 11 to set both to the same potential. When the board 2 is mounted on the frame 1 made of the metal, the GND terminal of the board 2 is electrically connected to the frame 11.</p> |
