Abstract:
A method for manufacturing a piezoelectric vibrator unit comprising the steps of:preparing a piezoelectric diaphragm 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 a back face thereof and one end portion of the individual electrode is exposed on a front face thereof; securing a substrate not related to the vibration onto one side end of the piezoelectric diaphragm; forming a first conductive layer conducting to the common internal electrode and extending to the front face of the diaphragm on which the individual electrode is exposed via an end face of the substrate; forming a second conductive layer conducting to the individual electrode so as to make a clearance with respect to the first conductive layer; securing a side face of the substrate on which the first conductive layer is formed to a fixing substrate; and forming a groove parting at least the second conductive layer and that area to be a vibrational area in accordance with an arrayed pitch of piezoelectric vibrators.
