An atomic oscillator includes a light source, a first coil initiating the light source to emit light, a resonance cell having enclosed atoms absorbing light from the light source, a second coil adjusting the resonant frequency of the atoms in the resonance cell, a resonator supplying the microwave of a predetermined frequency to the resonance cell, a control circuit generating a control voltage corresponding to a light absorption amount in the resonance cell according to the microwave frequency, and an oscillator having an output signal frequency controlled to the resonant frequency by the control voltage, wherein the first and second coils and the resonator are formed of a conductor pattern on a rigid-flexible substrate having a rigid portion and a flexible portion, and the flexible portion is wound on the periphery of the light source and the resonance cell, and connected to a connector disposed on the rigid portion.
