Abstract:
A liquid circulation device includes a supply unit that forms a flow path supplying a liquid from a reservoir unit; a collection unit that forms a flow path collecting the liquid to the reservoir unit; and N number of the connection units provided respectively corresponding to N number of ejection units ejecting the liquid forming a flow path connecting the supply unit and the collection unit via the ejection units, wherein with regard to each of N number of the connection units, a connection order of the connection units with respect to the supply unit, which is counted from upstream in a flow direction of the liquid in the supply unit coincides with a connection order of the connection units with respect to the collection unit, which is counted from upstream in the flow direction of the liquid in the collection unit.
