ABSTRACT:
An ink jet recording head comprising energy generating elements for applying the heat energy to the ink, heat acting portions for forming bubbles in the ink with said energy generating elements, a heat storing layer having insulating property for storing the heat energy disposed adjacent to said energy generating elements, and a support substrate for supporting said heat storing layer, characterized in that said support substrate is composed mainly of metal, and said heat storing layer is a chemical conversion coating which is formed through chemical treatment of the surface of said substrate.
