To provide a cartridge and a liquid injection system such that even if a case of the cartridge is pressurized to swell to deform, a possibility that a terminal of a circuit board becomes defective in contacting can be suppressed.SOLUTION: A cartridge has a terminal arrangement wall part 88 where a plurality of cartridge-side terminals 144 are so arranged as to form an inclined surface facing in a direction including a -Y-directional component and a +Z-directional component. The terminal arrangement wall part 88 includes: a first projection 155 and a second projection 165 which are provided more in a -Y direction than a second wall 82 constituting a pressurization chamber; a first drawn part 156 which extends in the -Y direction from the first projection 155; and a second drawn part 166 which extends in the -Y direction from the second projection 165. A first cartridge-side contact part capable of contacting a first device-side contact part is provided at the first drawn part 156, and a second cartridge-side contact part capable of contacting a second device-side contact part is provided at the second drawn part 166.SELECTED DRAWING: Figure 8 【課題】加圧によってカートリッジのケースが膨らんで変形しても、回路基板の端子が接触不良となる可能性を抑制できるカートリッジおよび液体噴射システムを提供する。【解決手段】カートリッジは、−Ｙ方向の成分および＋Ｚ方向の成分を含む方向を向く傾斜面を形成するように複数のカートリッジ側端子１４４が配置された端子配置壁部８８を有する。端子配置壁部８８は、加圧室を構成する第２壁８２よりも−Ｙ方向に設けられる第１の突部１５５と第２の突部１６５と、第１の突部１５５から−Ｙ方向に延びる第１の延伸部１５６と、第２の突部１６５から−Ｙ方向に延びる第２の延伸部１６６と、を含む。第１の装置側接触部と接触可能な第１のカートリッジ側接触部は、第１の延伸部１５６に設けられ、第２の装置側接触部と接触可能な第２のカートリッジ側接触部は、第２の延伸部１６６に設けられる。【選択図】図８
