Abstract: A liquid discharge head comprises discharge ports for discharging the liquid, a bubble producing area for producing an air bubble in the liquid of liquid flow channels, and a movable member, which is disposed toward the bubble producing area, and displaceable between a first position and a second position farther away from the bubble producing area than the first position, the liquid discharge head discharging the liquid in such a manner that the movable member is displaced from the first position to the second position by a pressure due to a bubble produced in the bubble producing area, and the bubble is more greatly expanded downstream than upstream in a direction toward the discharge port, due to the displacement of the movable member. The head has a check valve disposed in a liquid supply passage leading to the liquid flow channels.
