摘要：
A liquid discharge head is provided with discharge ports for discharging liquid, liquid flow paths communicated with the discharge ports for supplying liquid to the discharge ports, a substrate having heat generating members for creating bubbles in the liquid, and movable members facing the heat generating members and being arranged in the liquid flow paths. The movable members have a free end on the discharge port side with a specific gap with respect to the heat generating members. The movable member is fixed to the substrate above the heat generating member on the substrate.
