摘要： An oscillation circuit includes a circuit for oscillation and a signal adjustment circuit connected to the circuit for oscillation. An input voltage based on a direct-current voltage, a voltage value of which can be changed, is input to the circuit for oscillation and the signal adjustment circuit. The circuit for oscillation causes a vibration piece to oscillate and outputs a first oscillation signal. A frequency of the first oscillation signal is adjusted according to the voltage value output from the signal adjustment circuit.
