摘要： A method for manufacturing ink jet recording heads includes the steps of forming a film of a first inorganic material in the form of ink flow path pattern using a soluble first inorganic material on the substrate having ink-discharge, pressure-generating elements formed thereon, forming a film of a second inorganic material becoming ink flow walls on the film of the first inorganic material using the second inorganic material, forming ink-discharge openings on the film of the second inorganic material above the ink-discharge, pressure-generating elements, and eluting the film of the first inorganic material. With this method, it becomes possible to set the ink-discharge, pressure-generating elements and the ink-discharge openings (ports) of each head with extremely high precision in a shorter distance with a good reproducibility to record images with higher quality and without any deformation of the head due to the applied heat, while providing a good resistance to ink and erosion, as well as a higher dimensional precision and reliability that may be affected otherwise by swelling or the like.
