摘要：
A liquid discharge head at least comprises a discharge opening for discharging the liquid, a liquid flow channel in communication with the discharge opening and for supplying the liquid to the discharge opening, a substrate equipped with a heat generator for producing a bubble in the liquid that is filled in the liquid flow channel, and a movable plate supported and fixed onto the substrate at a position of the substrate opposed to the heat generator and with a gap from the substrate, with a free end on the discharge opening side. The liquid discharge head can discharge the liquid from the discharge openings by forcing the free end of the movable plate to be displaced toward the discharge opening around a fulcrum portion made near a support and fixing portion of the movable plate with the substrate due to pressure caused by produced bubble.
