1. A resonator comprising:
- a vibrating portion having a conductor portion; and
three or more insulating portions embedded in the conductor portion so as to electrically separate the conductor portion into a plurality of blocks;
wherein when a potential difference is caused across both ends in each of said three or more insulating portions, said vibrating portion carries out a resonance vibration based on a longitudinal vibration in accordance with a frequency of an A.C. signal inputted to each of corresponding ones of said plurality of blocks in said conductor portion.
