PROBLEM TO BE SOLVED: To provide an ink cartridge of simple structure and an ink jet recorder in which erroneous mounting of the ink cartridge can be determined easily and surely and cost reduction is promoted by making common the components. SOLUTION: A circuit board 39 is fixed to the front face 31a of an ink cartridge 30 at different positions for different kinds of ink in the ink cartridge 30. A connection mechanism 29 is made through the wall part 22b of an ink cartridge holder 22 at different positions for different kinds of ink. Erroneous mounting of the ink cartridge 30 is determined by detecting the relation of electrical connection between the circuit board 39 and the connection mechanism 29 at a control section 19 on the body side of an ink jet recorder 11. |
