摘要
A liquid discharge head includes a discharge port for discharging liquid, a liquid flow path communicating therewith and provided with a heat generating member for generating bubbles by heating the liquid, and a common liquid chamber for retaining the liquid to be supplied to the liquid flow path. A narrowed portion is provided in the liquid flow path between the common liquid chamber and the heat generating member. Between the narrowed portion and the heat generating member, a displaceable plate type movable member is provided. The movable member stands up from the surface of the liquid flow path having the heat generating member, in a direction substantially perpendicular to the liquid supplying direction. A first gap is provided between the narrowed portion and the movable member, and a second gap is provided between a free end of the movable member and a ceiling of the liquid flow path.
