Abstract
A method of manufacturing a liquid discharge head having an opening for discharging liquid droplets, a wall member constituting a liquid flow path to the opening, a substrate provided with and for creating a bubble in the liquid, and a movable member supported by and fixed to the substrate with the discharge opening side thereof as a free end displaced away from the substrate by pressure produced by creating the bubble to thereby direct the pressure to the discharge opening side including the steps of preparing the substrate and movable member, filling the gap between the movable member and the substrate with a liquid photo-curing resin, spin coating the resin until the resin covers the movable member, exposing an area of the resin to light to harden a portion corresponding to the wall member, and removing the unexposed portion of the photo-curing resin.
