Abstract
A liquid circulating device has: a supply flow path through which a liquid is supplied from a liquid supply source that stores the liquid to a liquid ejecting head that ejects the liquid; a collection flow path through which the liquid collected from the liquid ejecting head is returned to the supply flow path; and a liquid flowing portion that causes the liquid to flow in a circulation flow path including the supply flow path, the liquid ejecting head, and the collection flow path. An air capturing portion can capture bubbles and is provided in at least one of the supply flow path and collection flow path. The air capturing portion is disposed at a position higher than the position of the liquid ejecting head.
