A liquid discharge head capable of accurately discharging small droplets without generating scum at the discharge port and a method for manufacturing the same are provided. A step of providing a solid layer 3 for forming a flow path on a substrate 1 on which an energy generating element 2 is arranged, and a covering layer 4 for covering the solid layer on a substrate provided with the solid layer are formed. A step of forming a discharge port 7 for discharging a liquid onto a coating layer formed on the solid layer by a photolithography process, and a flow path communicating with the energy generating element and the discharge port by removing the solid layer The material for forming the coating layer includes a cationically polymerizable compound, a photocationic polymerization initiator, and a photocationic polymerization inhibitor, and is a solid layer, which is a discharge layer for the coating layer. The material that forms the boundary with the location where the outlet is formed includes a copolymer of methacrylic anhydride and methacrylic acid ester. A liquid discharge head manufactured by this method. [Selection] Figure 1 |
