Method of manufacturing an ink jet recording head
A method for manufacturing an ink jet recording head, which is provided with a first base plate having energy generating elements, a second base plate having grooves for forming ink flow paths corresponding to the energy generating elements, and a discharge port forming member for forming discharge ports for discharging ink. The method includes the steps of forming the discharge ports by irradiating the discharge port forming member with laser light reflected from the groove wall faces, and direct laser light, and forming the flow paths by bonding the base plate and the second base plate with the grooves inside.
