Abstract: The cartridge is attached to the cartridge attachment through an attaching operation in which the cartridge is completely inserted into the cartridge attachment in an insertion direction, or a horizontal direction, and then a rear portion of the cartridge in the insertion direction is moved in a rotation attaching direction containing a gravity-directional component with a deep side of the cartridge in the insertion direction used as a rotation fulcrum. This cartridge includes: a main body a liquid reservoir that is disposed inside the main body; a liquid inlet that is formed across the main body and leads to an interior of the liquid reservoir; a liquid reservoir body that includes a liquid supply section through which communicates with the liquid reservoir; and an adapter that is mounted on the liquid reservoir body and has an insertion aperture into which the liquid introduction section is to be inserted.
