1. An IC memory card comprising:

  • (a) an electrically insulating card case having a row of openings for receiving terminal pins of a read/writer and an interconnector receiving chamber communicating with said openings;

    (b) a printed wiring board fixed to said card case and carrying an IC memory, said printed wiring board being provided with a lead terminal which is disposed in said interconnector receiving chamber and is electrically connected with said IC memory at positions corresponding to said openings;

    (c) an interconnector being conductive in a direction of thickness and being made of an anisotropic conductive rubber, said interconnector being mounted in said interconnector receiving chamber and being, at one end of the direction of thickness, electrically coupled with said IC memory and being at the other end adapted to engage the terminal pins when the terminal pins are inserted through said openings, whereby the terminal pins are electrically conducted with said IC memory; and

    (d) a second interconnector in said card case mounted on a second interconnector receiving chamber and a second printed wiring board identical with said printed wiring board in said card case, and wherein said row of openings and said interconnector receiving chamber are disposed one over the other in said card case, wherein the two printed wiring boards are disposed on opposite surfaces of said card case, there being an IC memory carried by each of said printed wiring boards.
