Abstract
A motor includes a stator and a substrate. The stator includes a plurality of magnetic bodies and a coil wound around each of the magnetic bodies. The substrate opposes the stator in the rotational axis direction. The coil includes a first layer and a second layer stacked on the first layer. 1≤D/L holds, where L is a thickness of the magnetic body in the rotational axis direction and D is a width of the magnetic body in a radial direction. In the radial direction, a conducting wire of the first layer and a conducting wire of the second layer making up an inner edge of the coil are in contact with each other, and, in the radial direction, a conducting wire of the first layer and a conducting wire of the second layer making up an outer edge of the coil are in contact with each other.
