ABSTRACT:
An ink jet printer head fabricating method includes forming electrodes on surfaces of plural grooves by an electroless plating method using a wet process, the plural grooves being formed in a laminate substrate of two piezo electric members, cutting a portion of the laminate substrate with a dicing saw, and subsequently removing burrs of the electrodes by brushing with a brushing device. Burrs of the electrodes formed on the surfaces of the grooves are removed by the brushing without chipping or cracking of the electrodes, thereby preventing defects in ink ejection.
