Abstract
Abstract An IC card is disclosed, which comprises an IC pellet electrically connected to lead patterns via an anisotropically conductive adhesive layer. The IC pellet is also bonded to a print layer formed on an insulating film. A base sheet and another insulating film are laminated on the insulating film with the IC pellet sealed by resin in an IC pellet accommodation space formed in the base sheet.
