Abstract
A liquid ejecting method for ejecting a liquid includes using a liquid ejecting head having an ejection outlet portion having an ejection outlet for ejecting the liquid, a liquid flow path in fluid communication with the ejection outlet portion, a bubble generation region for generating a bubble in the liquid, and a movable member disposed to face the bubble generation region and provided with a free end closer to the ejection outlet portion than a fulcrum portion thereof, and displacing the movable member by a pressure based on generation of the bubble from a position of a reference surface to a position of a maximum displacement, thereby ejecting the liquid, wherein a relation of 2&thgr;,−7°≦&thgr;,≦2&thgr;,+7° is satisfied where, with a reference of the reference surface, &thgr;,is an angle of the movable member at the maximum displacement thereof about the fulcrum portion and &thgr;,is an angle of an axis connecting the fulcrum portion with an intersecting point of a center axis of the ejection outlet with a connecting surface of the ejection outlet portion to the liquid flow path, and wherein &thgr;,is an acute angle.
