ABSTRACT:
A method of manufacturing a liquid discharge head, comprising the steps of forming a film of an inorganic material in the form of a liquid flow path pattern on a substrate having liquid discharge elements formed thereon, forming a liquid flow path member on the film of the inorganic material using one of silicon oxide, silicon carbide, and carbon doped silicon oxide (SiOC), forming liquid discharge openings in corresponding portions above the liquid discharge elements, and eluting the film of the inorganic material so as to form a liquid flow path.
