Piezoelectric vibrator unit, method for manufacturing the same, and ink-jet recording head

摘要

One side face of a piezoelectric vibrator is fixed to a fixing substrate. A first conductive layer which conducts to a common internal electrode exposed on the side face in the side of the fixing substrate is formed on the front face of the piezoelectric vibrator which is an unfixed face. A second conductive layer which conducts to an individual internal electrode is formed on the front face. A flexible cable is connected to the front face.
