Claims8
A liquid ejection head that introduces a supplied liquid into a common liquid chamber through a filter and a liquid introduction path and generate pressure changes in a pressure chamber that communicates with the common liquid chamber by actuating a pressure generating unit, so that the liquid in the pressure chamber are ejected as liquid droplets through nozzles by using the pressure changes, comprising:
- a filter chamber that is disposed at an inlet opening of the liquid introduction path and is provided with the filter disposed therein;
- and
- a flexible film that is disposed on an inner wall of the filter chamber at a position downstream of the filter, wherein the flexible film is configured to deform in accordance with the pressure changes in the liquid introduction path.
