VIBRATOR AND METHOD OF MANUFACTURING THE SAME

摘要

A vibrator and a method for manufacturing the same are provided to simply and easily manufacture a surface mounting type piezoelectric filter by applying a multiple piezoelectric substrate to a whole laminating method. A vibrator includes main piezoelectric substrates(10,30), a pair of sub piezoelectric substrates(20,40), and a pair of piezoelectric elements(100,200). The main piezoelectric substrates include an inner electrode including divided electrodes formed by being separated from each other at a regular interval in a predetermined area of a side of the main piezoelectric substrates and common electrodes corresponding to the divided electrodes in a predetermined area of the other side of the main piezoelectric substrates. The sub piezoelectric elements have a piezoelectric property. The piezoelectric elements are connected by the main and the sub piezoelectric substrates.
