An electromagnetic valve driver includes: an electric power feeder configured to apply a power voltage obtained by switching a battery voltage to one end of an electromagnetic coil of an electromagnetic valve; a detector configured to detect a drive current flowing through the electromagnetic coil; and a power supply configured to supply power to the detector. The electric power feeder adjusts the drive current by operating in a state in which the power voltage is applied to the electromagnetic coil on the basis of a detection value of the detector. The power supply supplies the power obtained by sampling and holding a reference power in a period excluding a switching period of the battery voltage in the electric power feeder to the detector.
