Claim:
1. A piezoelectric device comprising: a piezoelectric vibration element; a temperature sensor that detects temperature; an insulating substrate having: a metal sealing member that is provided on a second part of the first surface so as to surround the piezoelectric vibration element in a plan view; a metal lid member that seals the piezoelectric vibration element relative to the first surface, the metal lid member being connected to the metal sealing member; a heat transfer metal member that is provided at the insulating substrate, wherein the heat transfer metal member extends from the temperature sensor mounting pad to the metal sealing member on an inner surface of the insulating substrate or through inside of the insulating substrate so as to thermally connect the temperature sensor and the metal lid member.
