PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid discharge head capable of controlling shapes and dimensions of a liquid channel and a liquid channel wall with high accuracy.SOLUTION: A method for manufacturing a liquid discharge head having a substrate having a liquid discharge energy generation element, an orifice plate having a liquid discharge port, and liquid channel walls disposed between the substrate and the orifice plate for forming a liquid channel communicating with the liquid discharge port, the method includes the steps of: (1) forming a first layer by coating a side on which the liquid channel walls are formed of surfaces of the substrate having the liquid discharge energy generation element with material for forming the liquid channel wall; (2) forming a second layer that is the orifice plate on the first layer; (3) forming the liquid discharge port on the second layer; (4) exposing a pattern of the liquid channel walls on the first layer via the second layer; and (5) forming the liquid channel walls by developing the pattern. |
