    摘要： An ink jet recording head comprises a substrate including a heat-generating resistance layer disposed on a support to provide a heat-generating section with two ends, a pair of electrodes on the support being connected electrically to the ends of the heat-generating sections. A member, joined to the substrate, has a recessed portion for forming a liquid pathway connected to an orifice for ejecting liquid. The member and substrate are joined so that the ends of the heat-generating section correspond to the liquid pathway. An organic material protective layer on the electrodes proximate to the ends of the heat-generating section is omitted from the heat-generating section and in the vicinity of an edge of the support where the liquid pathway is connected to the orifice. This configuration prevents the organic material protective layer from being subjected to the high temperatures attained by the heat-generating section and to the mechanical stresses encountered when the edge of the head is machined.
