摘要： A liquid ejection head has a heat generating surface for generating heat for generating bubbles in liquid, the heat generating surface being substantially flush and/or smoothly continuous with an upstream surface of the heat generating surface, a portion above the upstream surface and a further upstream portion being in fluid communication with each other when the heat generating surface does not generate heat, a movable member having a free end and a fulcrum, the movable member and the heat generating surface having a space therebetween, and an ejection outlet for ejecting liquid through generation of the bubble. The ejection outlet opposes the heat generating surface with the movable member interposed therebetween, and an opposing member cooperates with the movable member to direct the bubble toward the ejection outlet. The movable member directs the growing bubble toward the ejection outlet in a direction substantially perpendicular to the heat generating surface.
