Abstract

A liquid ejecting head for ejecting liquid by generation of bubble includes an ejection outlet for ejecting the liquid; a liquid path in fluid communication with the ejection outlet; a bubble generation region for generating the bubble in the liquid; a movable member having a fulcrum and a free end and disposed faced to the bubble generation region; wherein the movable member moves from the first position to the second position by pressure produced by the generation of the bubble, and a resistance against movement of the movable member, is smaller adjacent the free end than adjacent the fulcrum.
