  • Patent number: 7370415
    Abstract: A method for manufacturing an inkjet print head with ink channels formed on a member including a piezoelectric body, and where ink is jetted from each of the ink channels by applying a voltage to electrodes provided on the piezoelectric body for each of the ink channels thereby driving the piezoelectric body. The method has the steps including adsorbing a catalyst onto the channel plate with the ink channel grooves; removing a part of the catalyst by a laser beam; and plating at least one side surface and a bottom surface of the channel plate to form a layer which serves as the electrodes, on the catalyst which has not been removed by the laser beam.
