<p>PURPOSE:To enhance the reliability of this card by enhancing the bending rigidity of a card case by reinforcing said case by forming the part corresponding to the electronic circuit part of the card case from a metal plate material. CONSTITUTION:In each of upper and lower cases 7a, 7b, the part corresponding to an electronic circuit part 6 is formed into a metal case part 11 composed of a metal plate material, and the part corresponding to a transmitting and receiving part 5 is formed into a resin case part 12 composed of a synthetic resin material. The metal case part 11 enhances the bending rigidity of a card and the resin case part 12 enables the transmitting and receiving operation of the transmitting and receiving part 5. The metal case part 11 is formed by punching and the resin case part 12 is fitted to the mounting hole parts 13 provided the respective plate surfaces of said case 11 and bonded thereto thus forming the upper and lower cases 7a, 7b.</p> |
