PROBLEM TO BE SOLVED: To provide a magnetic bearing control device that can prevent the deterioration of responsiveness at a magnetic bearing to a control signal and stably support a component to be supported. SOLUTION: An H-bridge circuit is constituted of a coil 2c of an electromagnet 2b and four switches S1 to S4. A current is fed in one or the other direction with respect to the coil 2c arranged at the center of the H-bridge circuit by switching the switches S1 to S4 in accordance with the comparison result of a comparison circuit 8 that compares a control signal for position-controlling a rotating body 1 and a reference signal.
