A time-to-digital converter includes a first oscillation circuit that starts oscillating at the transition timing of a first signal and generates a first clock signal having a first clock frequency, a second oscillation circuit that starts oscillating at the transition timing of a second signal and generates a second clock signal having a second clock frequency, a first adjustment circuit that adjusts the oscillation frequency of the first oscillation circuit based on a reference clock signal, a second adjustment circuit that adjusts the oscillation frequency of the second oscillation circuit based on the reference clock signal, and a processing circuit that converts the time difference between the transition timing of the first signal and the transition timing of the second signal into a digital value based on the first and second clock signals.
