PROBLEM TO BE SOLVED: To obtain higher discharging efficiency and discharging force by orienting the pressure transmission based on the bubble generation to the discharging opening side. SOLUTION: An element substrate 1 is provided with a heat generating member 2 for generating bubbles in a liquid in a liquid channel 10 by applying heat to the liquid. A movable member 31 is provided facing to the heat generating member 2. The movable member 31 has a free end 32 at a discharging opening 18 side so that it can be displaced away from the heat generating member 2 according to the pressure based on the bubble generation. A recessed part 60 elongating from the free end 32 to a flucrum 33 side is provided at the surface of the movable member 31 facing to the heat generating member 2. |
