ABSTRACT:
A base member of a piezoelectric resonator includes a laminated body having a plurality of piezoelectric layers which are alternately polarized in opposite directions along the longitudinal direction of the base member and inner electrodes provided between the piezoelectric layers. On a first side surface of the base member, each of two external electrodes is arranged so as to be connected to one of two groups of alternate inner electrodes. Cut portions for adjusting a frequency of the piezoelectric resonator to a higher frequency are respectively formed at edge portions of the base member at opposite ends in the longitudinal direction of a second side surface opposite from the first side surface of the base member.
