An electric motor includes a stator, a rotor provided to be rotatable with respect to the stator, and a driving circuit board including a power IC applying a driving voltage to the stator, a Hall IC detecting a rotation position of the rotor, and a control IC adjusting a phase of the driving voltage in accordance with a magnetic-pole-position signal from the Hall IC and rotation speed information calculated on the basis of the magnetic-pole-position signal. The Hall IC is provided at a position at which an advance angle is larger than zero when a rotation speed of the rotor is zero.
