Abstract
A highly compact piezoelectric resonator having excellent resonant characteristics and very small resonant resistance includes an upper electrode disposed on one of two main surfaces of a piezoelectric film and a lower electrode disposed on the other main surface of the piezoelectric film. The upper electrode includes a first external-signal extracting electrode, a first leading electrode, and three first vibrating electrodes. The lower electrode includes a second external-signal extracting electrode, a second leading electrode, and three second vibrating electrodes. The three first vibrating electrodes are arranged substantially perpendicularly to the three second vibrating electrodes via the piezoelectric film. Vibrating sections are located at positions where the first vibrating electrodes are arranged substantially perpendicularly to the second vibrating electrodes.
