PROBLEM TO BE SOLVED: To provide a technique that enables stable electrical connection of a cartridge side terminal group and an apparatus side terminal group, and also to provide a technique that enables downsizing of a cartridge, a printer and consequently a printing material supply system that is completed in a state where the cartridge is mounted in the printer.SOLUTION: A cartridge includes: first-fourth surfaces; a printing material supply port; a cartridge side terminal group that receives the force of the direction that has +Z axis direction component from an apparatus side terminal group; and a first cartridge side restriction part. The cartridge side terminal group includes a first terminal having a first outer part located closest to a +Y-axis direction side and a second terminal including a second outer part located closest to a -Y-axis direction side. The first cartridge side restriction part is located in the inside of the range without being located in the outside of the range between the first outer part and the second outer part about the Y-axis direction. |
