ABSTRACT:
A piezoelectric resonator includes a base member having a piezoelectric member at the center and dielectric members disposed at opposite ends. A plurality of internal electrodes are provided in the base member. The piezoelectric member layer at the center of the base member is polarized in the longitudinal direction of the base member in opposite directions at both sides of each internal electrode. The center section of the base member is used as a vibrating section. On the other hand, the dielectric members at both ends of the base member are not polarized and are used as capacitor sections. Adjacent internal electrodes are connected to external electrodes serving as input and output electrodes, respectively.
