A cartridge detachably mounted in a cartridge mounting portion of a printing device including a liquid introduction portion configured to receive a liquid, a device side terminal, a device side terminal positioning portion, and a device side supply portion positioning portion, the cartridge comprising: a cartridge side terminal configured to be electrically coupled to the device side terminal; a liquid supply portion configured to be coupled to the liquid introduction portion and configured to make the liquid flow to the liquid introduction portion; a terminal positioning portion that is configured to perform positioning by receiving the device side terminal positioning portion to regulate movement of the cartridge side terminal with respect to the device side terminal; and a supply portion positioning portion that is configured to perform positioning by receiving the device side supply portion positioning portion to regulate movement of the liquid supply portion with respect to the liquid introduction portion, wherein a first direction is a direction intersecting a second direction, the first direction being a direction in which the terminal positioning portion extends, the second direction being a direction in which the supply portion positioning portion extends, the cartridge further comprising: a front wall located on a side of an insertion direction in which the cartridge is configured to be inserted into the cartridge mounting portion; a rear wall that faces the front wall in a first facing direction along the insertion direction; a bottom wall at which the liquid supply portion is arranged; a top wall facing the bottom wall in a second facing direction intersecting the first facing direction; and a corner portion where the front wall intersects the bottom wall and where the cartridge side terminal is arranged, wherein the first direction is parallel to the first facing direction, the second direction is parallel to the second facing direction, the terminal positioning portion is a groove formed in the corner portion, the supply portion positioning portion is a recess portion formed in the bottom wall, characterized in that the supply portion positioning portion is located on an opposite side of the liquid supply portion from the cartridge side terminal in the insertion direction. a cartridge side terminal configured to be electrically coupled to the device side terminal;
