Abstract
Provided is a technique that can reduce at least one of various inconveniences in a sub-tank, such as stock management being complicated. The sub-tank includes: a consumable article containing portion; a sub-tank-side storage unit; and a case that can be detachably attached to multiple slots in a consumable article consumption apparatus and contains the consumable article containing portion. In a state before the sub-tank is first mounted in the slot, the sub-tank-side storage unit stores a sub-tank-side identifier configured to distinguish from another sub-tank, and in a state after the sub-tank is first mounted in the slot, the sub-tank-side storage unit further stores sub-tank-side consumable article information relating to an attribute of the consumable article replenished in a consumable article containing portion.
