摘要：
A liquid discharging head includes a discharge port and a liquid passage provided with bubble-generating means and a movable member. The liquid passage has one side which is closed, and one side which communicates with the discharge port and with a liquid supply port. The movable member has a free end on the closed side of the liquid passage and a fulcrum on the other side. The bubble-generating means is disposed on a wall of the liquid passage facing the free end of the movable member and facing a wall in which the liquid supply port is provided. The movable member is separated from the discharge port by a gap in the liquid passage corresponding to the bubble-generating means. The projected area of the movable member on the liquid supply port is larger than the opening area of the liquid supply port.
