PROBLEM TO BE SOLVED: To provide a longitudinal crystal resonator which is microminiature, has small equivalent series resistance R<SB>1</SB>, has a new cut so as to have a high quality coefficient Q value, and has an electrode configuration and a shape in which electromechanical converting efficiency is high. SOLUTION: In the crystal resonator provided with a vibrator, a connector and a supporter, the crystal resonator provided with the vibrator, the connector and the supporter is integrally formed by a particle method, at least a pair of electrodes having different polarities are oppositely disposed on top and bottom surfaces of the vibrator, and the crystal resonator is a longitudinal crystal resonator which vibrates in a longitudinal mode.
