An ink jet recording head is provided with a recording element substrate having a plurality of discharge energy generating elements for generating energy utilized for discharging ink droplets, a ceiling plate arranged on the recording element substrate having an ink chamber formed to retain ink in the ink paths corresponding to the plurality of discharge energy generating elements, and a base plate for use of a recording element substrate to hold the recording element substrate. For this ink jet recording head, the recording element substrate, the ceiling plate, and the base plate are structured by the same material, thus preventing the substrate and plates from being damaged by warping, cracking, and other causes due to temperature changes or the like. <IMAGE> |
