PURPOSE: A liquid discharge head is provided to exhibit excellent durability and reliability through a heater for discharge of a movable member in a liquid flow path. CONSTITUTION: A liquid discharge head comprises a substrate(1), a ceiling plate(3) connected to the substrate(1), a liquid flow path(7) formed between the substrate(1) and the ceiling plate(3), and a cantilever-like movable member(206) having a fixed end fixed to the substrate(1) and a free end extending into the liquid flow path(7). The movable member is formed of a lower protective layer, a heat generating resistive layer, a lower electrode layer, an insulating layer, an upper electrode layer, and an upper protective layer stacked from the side of the substrate in the mentioned order, wherein application of a voltage to a heat generating portion of the heat generating resistive layer causes bubbling of a liquid in the liquid flow path between the movable member(206) and the substrate(1) to discharge the liquid.
