Crystal unit with built-in temperature sensor

Abstract

A crystal unit with a built-in temperature sensor includes a container, a quartz-crystal vibrating piece and a temperature sensor, a lid member, and a pedestal. The quartz-crystal vibrating piece and the temperature sensor are mounted in the container. The temperature sensor is provided on a first principal surface of the container. The lid member is connected to the container and sealing the quartz-crystal vibrating piece and the temperature sensor. The pedestal made of crystal has a height higher than a height of the temperature sensor disposed in a region of the first principal surface other than a region where the temperature sensor is provided. The quartz-crystal vibrating piece has a portion above the temperature sensor and another portion connected and secured to the pedestal made of crystal.
