Abstract:
An oscillation circuit includes: an oscillation unit which includes a first terminal and a second terminal connected to a resonator, a third terminal, a fourth terminal to which at least one of a power supply potential and a signal for inspecting the resonator is applied, a first switching unit which switches modes of electrical connection between the first terminal and the third terminal, and a second switching unit which switches modes of electrical connection between the second terminal and the fourth terminal.
