Original Abstract Submitted
A liquid ejection head includes a recording element substrate and a supporting member. The recording element substrate includes ejection ports that eject liquid, pressure chambers that communicate with respective ejection ports and are supplied with the liquid, and a liquid supply path that supplies the liquid to the pressure chambers. The supporting member is joined with the recording element substrate via an adhesive. The liquid supply path faces a joining portion of the recording element substrate and the supporting member, and includes at least one recess portion on an inner surface of the liquid supply path.
