PROBLEM TO BE SOLVED: To increase degree of freedom on wiring layout in an oscillator.SOLUTION: An oscillator 1 includes a crystal resonator 2, an integrated circuit 3 for outputting a first oscillation signal at a first frequency which is a resonance frequency of the crystal resonator 2 and outputting a second oscillation signal which is at a second frequency different from the first frequency, and a housing part 10 for accommodating the crystal resonator 2 and the integrated circuit 3. The integrated circuit 3 includes a vibration element input terminal for accepting input of a signal from the crystal resonator 2, a vibration element output terminal for outputting a signal to the crystal resonator 2, a first signal output terminal for outputting a signal at the first frequency, and a second signal output terminal for outputting a signal at the second frequency. The housing part 10 includes a first wiring layer having a first wiring connected to the vibration element output terminal, and a second wiring layer having a second wiring connected to the first signal output terminal and a third wiring connected to the second signal output terminal. The first wiring is formed at a position at which at least a part of the second wiring overlaps if it is projected to the second wiring layer and the third wiring does not overlap. |
