The present invention realizes low power consumption at the time of an automatic frequency control circuit operation. An automatic frequency control circuit includes a mixing unit that generates a modulated signal from a reception signal according to a frequency of a local signal, a demodulation unit that demodulates the modulated signal supplied by the mixing unit, an error evaluation unit that generates a frequency error signal according to a duty of the demodulated signal supplied by the demodulation unit, a holding unit that holds a frequency setting of the local signal and updates the frequency setting according to the frequency error signal supplied by the error evaluation unit, and an oscillation unit that controls a frequency of the local signal according to the frequency setting supplied by the holding unit.
