PROBLEM TO BE SOLVED: To provide a method for more easily manufacturing a liquid discharge head having an orifice plate formed of silicon.SOLUTION: The method for manufacturing a liquid discharge head comprises the steps of: preparing a first substrate having an energy generating element at a front surface side thereof; forming a wall member, which is to be a wall for a liquid flow passage, at the front surface side of the first substrate; forming a mask having an opening on the wall member and forming a second substrate, which is composed of silicon and is to be an orifice plate, on the mask; and forming a liquid supply port in the first substrate and a liquid discharge port in the second substrate by supplying an etchant from a back surface of the first substrate, the back surface being a surface opposite the front surface. |
