Method of manufacturing ink jet recording head and ink jet recording head manufacturing by the method.

摘要

A highly reliable ink jet recording head excellent in mechanical strength, weatherability, ink resistance, and adhesion to the substrate (1, 10) is provided. For its production, a cationically polymerized curing product of an epoxy resin having a structural unit expressed by the following formula (I) or (II), is used as a resin material (5, 12) which coats an ink flow path pattern (4, 11) formed from a dissoluble resin on the substrate.
