LIQUID EJECTION HEAD

摘要

Provided is a liquid ejection head, including: a liquid chamber; a supply port; and a recording element substrate arranged at a position opposed to the supply port across the liquid chamber. The liquid chamber includes: a first surface connected to the supply port; and a wall surface extending in a direction away from the recording element substrate. The wall surface includes: a space chamber connected to the first surface; and a second surface connecting a wall surface of the space chamber and the recording element substrate to each other. An intersection portion of the wall surface of the space chamber and a plane extended from the first surface is more distant from the recording element substrate than a connection portion between the wall surface of the space chamber and the second surface.
