Claim 10:
11. An oscillator comprising:
a first resonator element;
a first package that accommodates the first resonator element;
a relay substrate on which the first package is mounted;
a heater element that is attached to the first package or the relay substrate;
a second package that accommodates the first package; and
a heat insulating member that is provided at least between the second package and the relay substrate or between the relay substrate and the first package,
wherein the relay substrate is a first semiconductor device including a heater control circuit configured to control the heater element, and
a second semiconductor device including an oscillation circuit configured to cause the first resonator element to oscillate and generate an oscillation signal is accommodated in the first package.
