Abstract:
1. A printer comprising an ink-jet recording head manufactured by a method of manufacturing an ink-jet recording head including a step of simultaneously patterning an individual electrode layer and a piezoelectric element layer after successively forming the individual electrode layer and the piezoelectric element layer on a substrate, the method comprising the step of: forming a groove for defining an individual electrode lead-out part in the substrate and filling a conductive material into the groove before forming the individual electrode on the substrate; and including an individual electrode main body formed in the step of patterning the individual electrode layer, wherein; the defined groove extends to a position at which the groove overlays the individual electrode main body; the individual electrode lead-out part is arranged to partly overlap the individual electrode main body; and the individual electrode lead-out part and the individual electrode main body connect with each other outside a region where the piezoelectric element and the individual electrode main body are in contact with each other.
