ABSTRACT:
A liquid ejection head has an element substrate on which a plurality of heaters for generating energy for ejecting liquid droplets are disposed, a nozzle forming member laminated on the main surface of the element substrate and including a plurality of nozzles each having an ejection port for ejecting liquid droplets, a bubble forming chamber in which bubbles are formed by a heater, and a supply path for supplying liquid from a supply chamber to the bubble forming chamber. The nozzle forming member has a portion located in the vicinity of the heaters on the supply path side where the height of the nozzles is reduced, whereby the height of the nozzles changes toward the supply chamber.
