A liquid discharge head comprises heating members for generating thermal energy to create bubbles in liquid, discharge ports forming the portions to discharge the liquid, liquid flow paths communicated with the discharge ports, at the same time, having bubble generating areas for enabling liquid to create bubbles, movable members arranged in the bubble generating areas to be displaced along with the development of the bubbles, and regulating portions to regulate the displacement of each of the movable members within a desired range, and with energy at the time of bubble creation, the liquid being discharged from the discharge ports. For this liquid discharge head, the regulating portions are arranged to face the bubble generating areas in the liquid flow paths, and then, with the essential contact between the displaced movable members and the regulating portions, the liquid flow paths having the bubble generating areas become essentially closed spaces with the exception of the discharge ports. With the structure thus arranged, it becomes possible to suppress the back waves in the direction toward the upstream side, and also, with the meniscus which is drawn into the discharge port quickly, it becomes possible to prevent the satellites, hence stabilizing the discharge amount of liquid for the enhancement of the quality of prints.
