Abstract
A quartz crystal oscillator as a resonation device includes a substrate, a quartz crystal resonator as a resonator attached with a heating element, terminals adapted to fix the resonator and the substrate to each other, and intermediate members having an electrical insulation property and lower in thermal conductivity than the terminals. The intermediate members intervene between the resonator and the substrate via the terminals, and a gap is disposed between the quartz crystal resonator and the substrate.
