ABSTRACT:
A piezoelectric resonator has a substantially rectangular-parallelpiped-shaped base member. The base member includes laminated piezoelectric layers which are polarized in the longitudinal direction of the base member such that the directions of polarization differ at adjacent piezoelectric layers. Internal electrodes are disposed between the piezoelectric layers. The internal electrodes each preferably comprise a plurality stripes dispose on main surfaces of the piezoelectric layers. On opposing side surfaces of the base member, the internal electrodes are alternately covered by at least two insulating films. The at least two insulating films cover different internal electrodes. External electrodes are disposed on the opposing side surfaces of the base member and are connected to internal electrodes.
