Abstract:
A liquid ejection head is disclosed. The liquid ejection includes a flow channel plate, the flow channel plate being formed from one thin plate, the flow channel plate being formed with one or more pressure generating chambers, a fluid resistance section which supplies liquid to the pressure generating chamber, and a nozzle hole which opposes the pressure generating chamber. The flow channel plate is made of a metal material, and wherein the flow plate includes the pressure generating chamber which is formed of a groove-shaped indentation; the nozzle hole which is formed at one end in a longitudinal direction of the groove-shaped indentation; and the fluid resistance section which is formed at the other end in the longitudinal direction of the groove-shaped indentation. The pressure generating chamber, the nozzle head, and the fluid resistance section are formed such that they deform the thin plate in a thickness direction.
