(57) Abstract: [PROBLEMS] To provide a liquid ejection head, a liquid ejection method, and the like that can prevent deterioration of durability of a movable member due to excessive downward displacement of the movable member that fundamentally controls generated bubbles. . A liquid discharge method includes a discharge port for discharging a liquid, a bubble generation region for generating bubbles in the liquid, and A liquid discharge head having a free end 32 and a movable member 31 provided with a fulcrum 33 is disposed so as to face the area 11, The free end 32 of the movable member 31 is displaced by the pressure based on the generation of bubbles in the bubble generation region 11, and the displacement of the movable member 31 ejects the liquid from the ejection port 18. When the position of the movable member 31 before bubbles are generated is the first position, displacement of the free end region of the movable member 31 to the bubble generation region 11 beyond the first position is restricted. |
