[0054] 1. The first reinforcing portion 326a is arranged at the connection between the positioning portion 323 and the first base surface 321a, and the second reinforcing portion 326b is arranged at the connection between the acting portion 325 and the second base surface 321b, so as to avoid the breakage of the positioning portion 323 or the acting portion 325 when the ink cartridge 100 is bumped.

[0055] 2. Since the positioning portion 323 and the acting portion 325 do not extend from the support surface 322, even if the reinforcing member 326 is arranged, it will not affect the stable support of the chip 31 by the support surface 322, so that the chip 31 can be stably supported.
