A power supply circuit includes: a first switching element pair having a high-side first switching element and a low-side second switching element; a second switching element pair having a high-side third switching element and a low-side fourth switching element; and a control section complementarily driving the respective switching elements in the first and second switching element pairs, in which the control section sets a buck-boost ratio in a third operation mode in such a way that a buck-boost ratio in a first operation mode and a buck-boost ratio in a second operation mode continuously change, and sets a switching duty of the first switching element pair and a switching duty of the second switching element pair on the basis of the buck-boost ratio in the third operation mode.
