Abstract
A liquid discharging head comprises a discharge opening for discharging a liquid, a bubble generation region for generating a bubble in a liquid, and a movable member disposed so as to face the bubble generation region and arranged as displaceable between a first position and a second position more distant from the bubble generation region than the first position, wherein the movable member has the narrowest space in the bubble generation region and is displaced from the first position to the second position by pressure based on generation of the bubble in the bubble generation region, and wherein the bubble is made to expand greater downstream than upstream with respect to a direction toward the discharge opening, by displacement of the movable member.
