Abstract

A piezoelectric device includes an insulating substrate, a piezoelectric vibration device that is mounted on a device mounting pad, a metal lid member that seals the piezoelectric vibration device in an airtight manner, an external pad that is arranged outside the insulating substrate, an oscillation circuit, a temperature compensation circuit, and a temperature sensor. The lid member and the temperature sensor or the lid member and the IC component are connected to each other so as to be heat-transferable, and a heat transfer member having thermal conductivity higher than that of the material of the insulating substrate is additionally included.

First claim

What is claimed is:

1. An oscillation equipment comprising:
a vibration device including a package, the package containing an insulating substrate and a lid;
a vibration element installed in the package;
an oscillation circuit that drives the vibration element;
a temperature compensation circuit that supplies a signal to the oscillation circuit for compensating temperature characteristics;
a temperature sensor installed in the package that outputs analog temperature inform…
