There is provided with a resonator which can correct the resonance frequency of a vibrator in a wide range and with a high accuracy and also provided with an oscillator using the resonator. In the resonator configured by the vibrator 101, electrodes 4, 5 disposed so as to oppose to parts of the surface of the vibrator 101 via gaps, and variable voltage sources 24, 25 for applying a voltage to both or one of the vibrator 101 and the electrodes 4, 5, each of the electrodes 4, 5 is configured by plural electrodes. The electrodes 4, 5 are respectively disposed via gaps close to the portions of the vibrator 101 having different vibration amplitudes. The DC voltages being applied are independently adjusted with respect to the electrodes 4, 5 which differ in distances from the shaft of the vibrator among the plural electrodes close to the vibrator 101.
