Claim 0:
1. A thermostatic type crystal oscillator comprising:
a crystal resonator including an IT-cut crystal blank;
a vibration control circuit configured to control a vibration frequency of the crystal resonator;
a temperature regulator configured to regulate a temperature of the crystal resonator within a set temperature range by repeating heating and cooling to the crystal resonator;
a heat conducting plate configured to function as a heat absorbing plate and a heat dissipating plate for the temperature regulator;
a temperature control circuit configured to control a temperature of the temperature regulator; and
a housing that accommodates the crystal resonator, wherein
the housing defines, inside the housing, a resonator accommodating space in which the crystal resonator is accommodated,
the temperature regulator is a Peltier element configured to be capable of forcibly heating and forcibly cooling the crystal resonator, and
the temperature range is set within a range of 30° C. to 50° C.
