Abstract:
An atomic oscillator includes a first unit and a second unit arranged to be separated from each other and a package including an internal space in which the first unit and the second unit are housed in a state in which the internal space is decompressed to pressure lower than the atmospheric pressure. The reflectance of the outer surfaces of the first unit and the second unit to an electromagnetic wave having a wavelength of 4 μm is equal to or higher than 50%.
