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 high emissivity layer that is disposed at a surface of the heat generating unit on a first lid side and that has an emissivity higher than an emissivity of the surface. In addition, a constituent material of the surface is silicon, and the emissivity of the high emissivity layer at room temperature is 0.5 or more.
