A blower fan includes a shaft including an outer circumferential surface, a rotor magnet arranged to rotate about a rotation axis together with the shaft, a stator arranged radially outwards of the rotor magnet in an opposing relationship with the rotor magnet, a substantially cylindrical holder unit arranged to rotatably support the shaft through a bearing, and an impeller arranged to rotate together with the shaft. The bearing includes a pair of axially spaced-apart bearing units. The rotor magnet and the stator are arranged between the bearing units. The bearing units and the stator are held on an inner circumferential surface of the holder unit.
