Abstract:
A liquid ejecting head for ejecting liquid by generation of a bubble, comprising:an ejection outlet for ejecting the liquid; a liquid flow path in fluid communication with said ejection outlet; a bubble generation region for generating the bubble in the liquid in said liquid flow path; a heat generating surface for generating heat to be utilized to generate the bubble in said bubble generating region, said heat generating surface being at least one of substantially flush with and smoothly continuous with a surface adjacent to and upstream of said heat generating surface; and a movable member having a fulcrum and a free end located downstream of said fulcrum, and disposed facing said bubble generation region, wherein said movable member moves from a first position to a second position by pressure produced by the generation of the bubble, and a resistance against movement of said movable member is smaller adjacent to said free end than adjacent said fulcrum.
