摘要：
A method for manufacturing a liquid discharge head, which is provided with discharge ports for discharging liquid; liquid flow paths communicated with the discharge ports for supplying the liquid to the discharge ports; heat generating elements arranged in the liquid flow paths for creating bubbles in the liquid; an elemental substrate having the heat generating elements therefor; and movable members arranged for the elemental substrate having each free end thereof on the discharge port side with a gap with the elemental substrate in the position facing the heat generating element on the elemental substrate, each free end of the movable members being displaced on the discharge port side centering on the fulcrum structured near the supporting and fixing portion with the elemental substrate by the pressure exerted by the creation of the bubbles for discharging the liquid form the discharge ports, comprises the steps of forming gap formation members; forming the material film; pattering the material film; and forming the gap.
