A method for producing an ink jet recording head, comprising steps of forming, on a substrate, a solid layer composed of soluble resin and having a pattern for constituting a liquid flow path; forming an inorganic film by low temperature film formation so as to cover the solid layer; forming a layer of a head forming material so as to cover the inorganic film; removing a part of the inorganic film for forming a discharge port; and removing the solid film thereby forming a liquid flow path communicating with the discharge port.
