Abstract
A piezoelectric resonator unit includes a base member having a mounting surface. A piezoelectric resonator is mounted on the mounting surface and a lid member is bonded to the mounting surface such that the piezoelectric resonator is hermetically sealed in an inner space. A heat conductor is connected to a temperature sensor that detects a temperature of the piezoelectric resonator and is connected to a heating element that radiates heat onto the piezoelectric resonator. The heat conductor has a portion that is arranged in the inner space.
