This DC-brushless-motor control device, which supplies a current to a winding of a stator of a three-phase DC brushless motor, controls the current-passage state of switching elements using, in order from a point in time at which the magnetic pole position detected by a magnetic-pole-position detection unit reaches a reference position, a plurality of states including: a first state in which a first switching element and a second switching element are both in an off state; a second state in which the first switching element is maintained in an on state, and the second switching element is maintained in an off state; a third state in which the first switching element and the second switching element are both in an off state; and a fourth state in which the first switching element is maintained in an off state, and the second switching element is maintained in an on state. |
