Title:
THERMOSTATIC BATH-TYPE PIEZOELECTRIC OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2022/050414
Kind Code:
A1
Abstract:
Provided is a thermostatic-bath-type piezoelectric oscillator in which the amount of heat emitted by a heater for maintaining the temperature of a core part can be kept as small as possible. A thermostatic-bath-type piezoelectric oscillator (1) in which a core part (5) having at least an oscillation IC (51), a crystal oscillator (50), and a heater IC (52) is enclosed in a sealed state inside a heat insulation package (2), wherein the core part (5) is supported on the package (2) with a core substrate (4) interposed therebetween, and, as seen in plan view, the core substrate (4) is connected to the package (2) outside the region in which the core part (5) is provided.
