Abstract: In an IC card with socket, a conductive member is attached to the front surface section of a socket housing into which the pin contacts of an IC card connector device (not shown) are inserted and electrically connected to a metal cover. With this arrangement, even if static electricity having a large amount of charge is charged to an operator, the static electricity is discharged to the conductive member and removed without discharging to socket contacts. Accordingly, the LSI in the IC card is not broken by the static electricity.
