Abstract:
1. A method of manufacturing an ink-jet recording head including a plurality of recording element substrates each having at least one nozzle array comprising a plurality of nozzles to eject ink, an electric wiring member arranged to supply signals to the plurality of recording element substrates, a supporting member arranged to support the plurality of recording element substrates and the electric wiring member, electric connecting portions electrically interconnecting the recording element substrates and the electric wiring member, and a sealant sealing the electric connecting portions, the method comprising the steps of: applying sealants to the supporting member including the recording element substrates, the electric wiring member, and the electric connecting portions, and curing the applied sealants by heating the sealants; measuring a distance between at least two reference positions set on each of the recording element substrates before and after the curing of the sealants; and mounting the plurality of recording element substrates to the supporting member depending on a difference in the distance between the reference positions measured in the measuring step before and after the curing of the sealants.
