ABSTRACT:
A method for making a liquid discharge head including liquid discharge openings, a liquid channel having pressure chambers communicating with the liquid discharge openings, and piezoelectric elements corresponding to the pressure chambers and arranged in the form of teeth of a comb includes the steps of filling gaps between the piezoelectric elements with a filler; forming a liquid channel pattern on a flat surface including the end faces of the piezoelectric elements and the filler filling the gaps between the piezoelectric elements; forming a coating layer on the liquid channel pattern; and removing the liquid channel pattern to form the pressure chambers.
