A method of manufacturing an ink jet print head that ejects ink from the channel by forming a channel in a member including a piezoelectric body, applying a voltage to an electrode provided on the piezoelectric body, and driving the piezoelectric body. Yes,
At least one side surface and bottom surface of a channel plate having a plurality of channel grooves are subjected to plating treatment by adsorbing a catalyst to form a thin plating film having a thickness smaller than a desired thickness. Ink-jet printing characterized in that an additional plating film is formed on the plating thin film that has not been removed by the laser beam by removing and then plating again, thereby forming the electrode having the desired film thickness. Manufacturing method of the head. A method of manufacturing an ink jet print head in which a channel is formed in a member including a piezoelectric body, a voltage is applied to an electrode provided on the piezoelectric body, and the piezoelectric body is driven to eject ink from the channel. ,
After adsorbing a catalyst to a channel plate having a plurality of channel grooves, a part of the catalyst is removed with a laser beam, and then at least one side surface and a bottom surface of the channel plate are plated, thereby the laser A method of manufacturing an ink jet print head, comprising forming a plating layer as the electrode on a catalyst that has not been removed by light. A method for manufacturing an ink jet print head that ejects ink from the channel by forming a channel with a member including a piezoelectric body, applying a voltage to an electrode provided on the piezoelectric body, and driving the piezoelectric body. Yes,
After forming a head chip by bonding a channel plate having a plurality of channel grooves and a cover plate, inner walls of a plurality of cylindrical channels formed on the head chip and a predetermined outer peripheral surface of the head chip Then, a catalyst is adsorbed to form a plating layer as the electrode, and then a part of the plating layer formed on the outer peripheral surface is removed with a laser beam, so that the electrodes corresponding to the plurality of channels are A method of manufacturing an ink jet print head, comprising forming an outer peripheral surface of a head chip. The plating layer formed as the electrode has a plating film thickness smaller than a desired electrode film thickness, and after removing a part of the plating thin film formed on the outer peripheral surface with a laser beam, the plurality of channels are again formed. By plating the inner wall and the predetermined outer peripheral surface, a further plating film is formed on the plating thin film that has not been removed by the laser beam, thereby forming a plating layer having a desired film thickness as the electrode.
