Provided is a switching control circuit used for a switching power supply device for generating an output voltage from an input voltage. The switching control circuit includes an intermittent operation mode for repeating an active period in which an output switching element of the switching power supply device is switched and an inactive period in which the output switching element is not switched. The switching control circuit is provided with a modulation unit for modulating a pulse frequency of a switching control signal during the active period, and performs control of switching of the output switching element by the switching control signal during the active period.
