PROBLEM TO BE SOLVED: To provide a control signal generation circuit and a circuit device that can suppress a deterioration in controllability of a high side switch and a low side switch caused by providing a dead time.SOLUTION: In a control signal generation circuit 1, a first delay circuit 11 outputs a delayed and logically inverted version of an input pulse signal. The first delay circuit 11 does not change a duty ratio of the input pulse signal. A signal inverted in a logical inversion element J21 from the output signal of the first delay circuit 11 is output as a high side control signal. A second delay circuit 12 outputs a delayed rise version of the output signal of the first delay circuit 11. A signal inverted in a logical inversion element J24 from the input pulse signal and a signal shaped in logical inversion elements J22 and J23 from the output signal of the second delay circuit 12 are input into an OR element A1, and an OR signal of both the signals is output as a low side control signal.
