ABSTRACT:
An IC memory card having a connector structure adapted to be connected with the terminal pins of an external read/writer. A card case has in its end surface a row of openings for receiving the terminal pins. An interconnector receiving chamber is disposed rearwardly of the row of openings and communicates therewith. In the interconnector receiving chamber, an elastic interconnector of anisotropic conductive rubber, which is conductive in the direction of thickness, is mounted. When the terminal pins are inserted, they are electrically conducted with a printed circuit board via the interconnector so that the connector structure inside the memory card can be automatically accomplished. The interconnector is in the form of a thin strip; the memory card can be assembled very simple by merely mounting this interconnector in the interconnector receiving chamber. A retainer plate of insulating rubber is placed over the interconnector to airtightly seal the latter from the external.
