Abstract:
A liquid ejection head includes a flow path substrate, a first plate having a nozzle, and a second plate. A flow path substrate includes a first communication path which passes through a flow path substrate in a thickness direction and has an opening on each of a first plate side and a second plate side, and a second communication path communicating with an opening on a first plate side of a first communication path at a first plate side and extending on the second plate side. A pressure chamber communicating with a first communication path and a first flow path through which a liquid flows into a pressure chamber are formed by a part of a second plate and a part of a flow path substrate.
