ABSTRACT:
A piezoelectric resonator which vibrates in a longitudinal vibration mode includes first insulating films disposed on a side surface of a base member so as to cover at least part of exposed portions of a first group of the internal electrodes and second insulating films disposed on the side surface of the base member so as to cover at least part of the exposed portions of a second group of the internal electrodes. A first thin-film external electrode extends continuously in the longitudinal direction of the base member on the first insulating films and a second thin-film external electrode extends continuously in the longitudinal direction of the base member on the second insulating film. A first conductive resin film and a second conductive resin film are respectively provided on the first thin-film external electrode and the second thin-film external electrode such that even if the thin-film external electrodes are broken or damaged, the piezoelectric resonator still functions.
