To miniaturize a circuit board mounted with a control circuit for controlling the rotation of a motor.
The motor includes a stationary section, a rotary section and a bearing. The stationary section includes a bearing holder in which the bearing is inserted, a base portion extending radially outward from under the bearing holder, a stator fixed to an outer circumference of the bearing holder, a circuit board 224 fixed on the base portion and partly overlapping the stator axially, and a sensor section 225. An angle formed by both circumferential end portions of the circuit board 224 and a center axis is below 180 degrees. The sensor 225 includes a package part 71 having a Hall element and circumferentially spaced apart from the circuit board 224, and a plurality of lead wires 72 extended parallel from the package part 71 to the circuit board 224 and connected to the circuit board 224. The package part 71 is positioned within a circle centered on the center axis J1 and passing the position of the circuit board 224 which is most distant from the center axis J1.
