た。2. Description of the Related Art In the manufacture of an IC card having a built-in primary battery, a method of integrally molding a card body and a battery and a manufacturing method of a film bonding structure are often adopted due to the reduction in thickness of the IC card. At the time of molding, the primary battery is connected. Therefore, the service life of the card starts from the time when the molding process is completed, and the service life guarantee from the time of shipment varies depending on the period of inventory in the factory. From the viewpoint of the battery life of the card, it is better to connect the battery at the time of shipment, but in order to inspect and test during manufacturing, it is necessary to connect the battery (power supply), which is an integral part. Difficult due to molding and film bonding structure.
