PROBLEM TO BE SOLVED: To solve the problem of the structure of the constant temperature bath of a constant temperature bath type quartz oscillator, of which the heat is sensed with a temperature sensor in the constant temperature bath and the current of a heater is controlled according to its change for temperature control, however, the change of the external temperature is not transferred quickly while much heat is released from a support. SOLUTION: The support is improved for less release of heat. A quartz oscillator is realized whose structure takes releasing of heat from the support into account for temperature control.
