Abstract:
A flow passage member is used in a liquid ejecting head including an ejecting unit. The ejecting unit communicates with a self-sealing unit which is a negative pressure generation mechanism. The flow passage member includes a flow passage internal pressure adjustment mechanism that adjusts a pressure inside a flow passage between the self-sealing unit and the ejecting unit by changing a volume of the flow passage on a way of the flow passage and a flow passage opening and closing mechanism that opens and closes the flow passage on a way of a flow passage between the self-sealing unit and the flow passage internal pressure adjustment mechanism.
