Abstract:
A piezoelectric vibrator unit comprising:a plurality of piezoelectric vibrators back faces of which are secured to a fixing substrate, each of the piezoelectric vibrator including a non-vibrational area and a vibrational area in which a common internal electrode and an individual internal electrode are laminated in a displacement direction thereof together with a piezoelectric material sandwiched therebetween so as to be wrapped in a central area thereof and such that one end portion of the common internal electrode is exposed on the back face and one end portion of the individual electrode is exposed on a front face thereof; a first conductive layer conducting to the each common internal electrode and extending to the each front face of the respective piezoelectric vibrators; and a second conductive layer conducting to the each individual internal electrode and formed on the each front face of the respective piezoelectric vibrators.
