An ink jet recording head having an ink pathway in communication with a jetting exit formed on a substrate on which an active element generating energy utilized for jetting out an ink is disposed, at least a portion of the ink pathway being constituted with a cured film of photosensitive resin, wherein the photosensitive resin composition comprises (a) a specific high molecular compound, (b) a photopolymerizable compound having two or more acryloyl groups or methacryloyl groups in one molecule, and (c) a photopolymerization initiator. The ink jet recording head can provide various merits, for example, (i) having satisfactory durability against change of heat under working circumstance, (ii) causing no defoliation between the ink pathway walls and other constituent members even under continuous long-time use, (iii) developing no crack to the ink pathway walls even for continuous long-time use, (iv) having satisfactory jetting durability, etc.
