Verfahren zur Herstellung eines Tintenstrahlaufzeichnungskopfs

摘要

A method for manufacturing an ink jet recording head, which is provided with a first base plate having energy generating elements (7) for generating energy utilized for discharging ink, and a second base plate (4) bonded to the first base plate which has grooves for forming ink flow paths (2) corresponding to said energy generating elements, and discharge port forming member (3) for forming discharge ports for discharging said ink integrally formed in front of the grooves, comprises the steps of forming the discharge ports by drilling the discharge port forming member with the reflecting light of laser beams reflected from the groove wall faces of the second substrate, and the direct light of laser beams on the discharge port forming member, and forming the flow paths by bonding the first base plate and the second base plate with the grooves inside. The ink jet recording head becomes capable of eliminating the deviation in flying directions of the main droplet and satellites on the forward and backward printing.
