摘要：
A liquid discharging head has at least a discharge port for discharging liquid therefrom, a liquid flow path communicating with the discharge port to supply the liquid to the discharge port, a substrate provided with a heating member for creating a bubble in the liquid filling the liquid flow path, and a movable member having a movable portion having its free end at the discharge port side and provided at a location facing the heating member of the substrate with a gap with respect to the substrate, a supported and fixed portion supported on and fixed to the substrate, and a supporting portion provided near the supported and fixed portion of the movable portion. The free end of the movable member is displaced toward the discharge port side about the fulcrum portion of the movable member by pressure produced by the bubble being created to thereby discharge the liquid from the discharge port. The movable member is formed of a silicon material and has a bent portion forming the gap, and the fulcrum portion has a curved surface shape.
