Abstract
A tank includes: a liquid container configured to store a liquid; an inlet opening through which the liquid flows into the liquid container; an outlet opening through which the liquid flows out from the liquid container; and a channel formation member arranged between the inlet opening and the outlet opening and configured to form channels. Widths of the channels are such that a channel at a position where stagnation of the liquid is more likely to occur has a larger width.
