PROBLEM TO BE SOLVED: To provide a liquid discharge head capable of discharging both main droplets and satellites in a desired discharging direction and having no variation in lives of heaters of chips A, B. SOLUTION: The liquid discharge head has two plate-like movable valves 6 discharging liquid by two air bubbles generated by heating and foaming the liquid by two heaters 2 arranged so as to face each other in a nozzle and displaced by receiving pressure caused by the generated air bubbles. In this case, a stopper 7 is formed in the discharge nozzle to regulate the movement of the movable valves 6 when the air bubbles are generated. COPYRIGHT: (C)2009,JPO&INPIT
