<p>PURPOSE:To eliminate loss of durability of a metal contact in contact with an electrode terminal by engaging small protrusions with small holes to integrate a card base with a circuit board, and exposing the terminal with a cutout between pectinated guides. CONSTITUTION:Small protrusions 32 are engaged with small holes 40 to be combined. An electronic component mounted on a circuit board 26 is contained in the recess of the rear surface of a card base 24, and the protrusions 32 protrude from the rear surface of the board 26. When the material of the base 24 is thermoplastic, the base 24 can be coupled with the board 26 by applying pressure to the protrusions while heating them. Accordingly, they can be combined without using a both-side adhesive tape or adhesive, and improper contact due to extension of the tape or the adhesive is eliminated. When an IC card is inserted into an opposite side connector, the metal contact 42 of the connector is contained in a cutout 30 in contact with an electrode terminal 38, thereby transmitting information.</p> |
