Abstract
With an ink cartridge mounted on a cartridge mounting section of a printer, an apparatus-side terminal elastically comes in contact with a container-side terminal of a container-side circuit substrate. The container-side terminal includes a curved edge portion at a corner portion in which a groove of a substrate surface comes in contact with a substrate end surface. Depths of the grooves in container-side terminals are different and positions of contact sections with the apparatus-side terminals are different in the edge portions. As a result, positions in directions in which elastic forces act from the apparatus-side terminals are different for each contact section and the elastic forces having values and directions which are not uniform act on the container-side circuit substrate at different positions. Thus, it is possible to suppress positional shift of the container-side circuit substrate and to suppress contact failure between the container-side terminal and the apparatus-side terminal.
