Classification: CPC H | IPC H

Claim 11:
12. 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 semiconductor device between the relay substrate and the first package;
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 heater element is fixed to the first package,
the semiconductor device includes a heater control circuit configured to control the heater element, and an oscillation circuit configured to cause the first resonator element to oscillate and generate an oscillation signal, and
at least the second package and the relay substrate, or the semiconductor device and the first package are bonded by the heat insulating member.
