Abstract:
1. A method for manufacturing a liquid discharge head including an energy generating element configured to generate energy that facilitates discharging a liquid, a discharge opening adapted to discharge the liquid, and a channel supplying the liquid to the discharge opening, the method comprising the following steps: a step of forming a lamination on a substrate provided with the energy generating element, such that the lamination includes a plurality of laminated negative photosensitive resin layers with a light shielding film pattern for forming the channel, the light shielding film pattern being disposed therebetween, wherein the step of forming the lamination on the substrate includes the steps of: a step of exposing a portion which is set to be a member consisting the channel of the negative photosensitive resin layers in the lamination using a discharge opening mask; and a step of removing an unexposed portion of the negative photosensitive resin layers in the lamination.
