Abstract
A liquid ejecting head includes a liquid ejecting section, a first-valve-unit adjusting a pressure of liquid to be supplied to the liquid ejecting section, and a housing accommodating the liquid ejecting section and the first-valve-unit, in which the first-valve-unit includes a first-flow-path communicating with the liquid ejecting section, a first flexible film that has a first-inner-surface defining a part of the first-flow-path and a first-outer-surface being opposite from the first inner surface, and is configured to displace in a first-direction from the first-outer-surface toward the first-inner-surface and in a second-direction opposite to the first-direction, and a first-valve-body that is moved between an opening position and a closing position, due to displacement of the first flexible film, and the housing has a first-opening-portion facing at least a part of the first-outer-surface.
