An apparatus (10) for driving an inductive load (13), includes a switching element (11) provided in a current flowing path of the inductive load (13), a diode connected to the inductive load (13) in parallel, a current detecting resistor (15) detecting current flowing through the inductive load (13), a peak hold circuit (17) holding voltage detected by the current detecting resistor (15) when the switching element (11) is on, when the switching element (11) is off, and a control section (23) controlling current flowing through the inductive load (13) by turning on/off of the switching element (11) at a duty ratio in response to a target current value while the control section (23) performs feedback control of output of the peak hold circuit (17). The control section (23) controls current that flows through the inductive load (13) when the duty ratio is larger than a threshold value and controls voltage that applies to the inductive load (13) when the duty ratio is smaller than the threshold value.
