A method for manufacturing an ink jet recording head, which is provided with a recording elemental substrate having discharge port group for discharging ink, an electric wiring substrate electrically connected with the recording elemental substrate, and a supporting member for holding and fixing the recording elemental substrate and the electrical wiring substrate, comprises the steps of injecting thermohardening filler into a filler retaining portion communicated with the sealing area requiring sealing; filling the area with the thermohardening filler injected into the filler retaining portion by heating the filler to flow; and hardening the filled thermohardening filler. With the structure thus arranged, it is possible to eliminate any electrical and structural defects in order to materialize a highly reliable and compact ink jet recording head.
