Producing method for ink jet recording head

摘要

It is disclosed a method for producing an ink jet recording head including a plurality of recording element substrates (H1100,H1101) each including a recording element (H1103) for generating energy to be used for ink discharge and an electrode portion (H1104) connected to said recording element; a wiring substrate (H1300) provided with electrode terminals (H1302) to be electrically connected with said electrode portions of said plural recording element substrates, respectively, and adapted to transmit an electrical pulse for ink discharge to said recording elements, respectively; and an element substrate support member (H1200) for supporting said plural recording element substrates. The method comprises a step of causing said plural recording element substrates to be supported on said element substrate support member; and a step of thereafter executing bonding between said electrode portions of said plural recording element substrates and said electrode terminals of said wiring substrate, respectively.
