Abstract
In the oscillator, a quartz crystal resonator and an oscillation circuit formed in an IC incorporating an inductor are electrically coupled to each other with a resonator interconnection disposed on a surface of a substrate to form an oscillation loop. A conductor layer disposed as an intermediate layer of the substrate is disposed so as to overlap the resonator interconnection and not to overlap the inductor incorporated in the IC in a plan view.
