摘要：
A circuit board (27) on an ink cartridge (9) has contact pads which are electrically conducted to a semiconductor storage element (65) mounted on the circuit board. Connector terminals on an ink jet recording apparatus are brought into relative slide contact with a surface of this circuit board, and electrically connected to the contact pads. When the connector terminals come in contact with the contact pads, the dust adhering to the connector terminals (70) is wiped and removed by step portions that are constituted by no-resist-film formation parts and that are adjacent to the contact pads. Consequently, the reliability of the electrical contact between the connector terminals and the contact pads is ensured.
