Abstract
A resonator device includes: a resonator element; a heat generating unit; a first package including a first base at which the resonator element and the heat generating unit are disposed, and a first lid bonded to the first base so as to accommodate the resonator element between the first lid and the first base; and a low emissivity layer that is disposed at an inner surface of the first lid and that has an emissivity lower than an emissivity of the first lid. In addition, a constituent material of the first lid is silicon, and the emissivity of the low emissivity layer at room temperature is less than 0.5.
