A motor for holding a disk with a mounting opening in place includes a rotor unit including a rotor magnet rotatable about a central axis and a stator unit including a stator arranged opposite to the rotor magnet and a circuit board electrically connected to the stator. Wiring lines of the circuit board include output-side land portions electrically connected to first ends of coils of the stator, a connection-side land portion electrically connected to second ends of the coils forming a neutral point, a connection portion electrically connected to an external power source, output-side wiring portions arranged to electrically interconnect the output-side land portions and the connection portion, and a connection-side wiring portion arranged to electrically interconnect the connection-side land portion and the connection portion. Each of the output-side wiring portions has a width greater than a width of the connection-side wiring portion.
