1. A cartridge detachably attached to a cartridge attachment section of a printing apparatus, the cartridge comprising:
a first operation surface that is positioned on a front side in an inserting direction which extends in a horizontal direction and in which the cartridge is inserted into the cartridge attachment section in an inserted posture in which the cartridge is inserted into the cartridge attachment section, the first operation surface being pushed in the inserting direction to receive a first load for moving the cartridge in the inserting direction;
a main surface that constitutes a top surface positioned on a side of an upward direction in a direction of gravity in the inserted posture; and
a second operation surface that constitutes the top surface in the inserted posture and is positioned on a side of a downward direction in the direction of gravity with respect to the main surface, the second operation surface being pushed in the downward direction in the direction of gravity to receive a second load for moving the cartridge in a rotational-attachment direction having a component in the downward direction in the direction of gravity, wherein
in side view in which the cartridge is viewed in a width direction orthogonal to the inserting direction and the downward direction in the direction of gravity in the inserted posture,
an angle formed by the second operation surface and the inserting direction is smaller than an angle formed by the first operation surface and the inserting direction.
