| 摘要 |
The present invention relates to an ink jet printer head fabricating method involving 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 constituted by a laminate of two piezoelectric members, cutting off an end face of the laminate substrate which end face is located on an open side of the grooves, by means of 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 completely without chipping or cracking of the electrodes, thereby preventing defects in ink ejection such as misdirection, i.e., failure to make a straight flying of ink droplets, and unstable flying of ink.
