摘要： There is provided a method for manufacturing a liquid discharge head including a liquid discharge head substrate and a flow path forming member, the liquid discharge head substrate having a base, a pressure generation portion provided at a front surface of the base to generate pressure for discharging a liquid, and a supply port for supplying the liquid to the pressure generation portion, and the flow path forming member forming a flow path for feeding the liquid supplied from the supply port to the pressure generation portion. The method includes removing a sacrificial layer by etching the base from a back surface of the base, in a state in which an end covering portion of a cover layer for covering the sacrificial layer is covered with the resin layer. The method suppresses formation of a crack in the end covering portion that covers the end portion of the sacrificial layer.
