PURPOSE: A method for manufacturing a liquid discharge head is provided to discharge a predetermined liquid due to a bubble generated by heat energy and to exhibit a reduced manufacturing time and a film thickness of several dozen microns. CONSTITUTION: A liquid discharge head includes a discharge opening(5) for discharging liquid droplets therefrom, a wall member constituting a liquid flow path(7) communicating with the discharge opening(5) to supply liquid to the discharge opening, a substrate provided with a bubble creating element for creating a bubble in the liquid, and a movable member(6) supported by and fixed to the substrate with the discharge opening side thereof as a free end and provided at a position facing the bubble creating element in the liquid flow path(7) with a gap between it and the substrate, wherein the free end of the movable member(6) being displaced away from the substrate by pressure produced by creating the bubble to thereby directs the pressure to the discharge opening side and discharges the droplet of the liquid from the discharge opening(5). A method for manufacturing the liquid discharge head has the steps of preparing the substrate provided with the movable member, filling the gap between the movable member and the substrate with liquid photo-curing resin and applying the resin to the substrate by spin coating until it covers the movable member, exposing that area of the photo-curing resin which excludes an area including at least the liquid flow path to light to thereby harden a portion corresponding to the wall member, and removing the unexposed portion of the photo-curing resin to thereby form the movable member in the liquid flow path. |
