Abstract

A method produces a liquid ejecting head having an ejection outlet for ejecting a liquid, a heat generating element for applying thermal energy to said liquid, a liquid flow path comprised of a first path portion in fluid communication with said ejection outlet and a second path portion disposed below said first path portion and provided with said heat generating element in a bottom surface thereof, a partition wall for partitioning said liquid flow path into said first path portion and second path portion, and a movable member disposed above said heat generating element in said portion wall and arranged as displaceable to a side of the first path portion in accordance with a bubble generated in the liquid by said thermal energy in which upon generation of said bubble the first path portion and the second path portion are in fluid communication with each other and said pressure is directed toward said ejection outlet by said movable member displaced to eject said liquid droplet. The method comprises a step of preparing a substrate provided with said heat generating element, a step of forming a grooved partition wall having said movable member and side walls of said second path portion, and a step of joining said grooved partition wall to said substrate to form said second path portion.
