Motor and disk drive apparatus

A motor for holding a disk with a mounting opening in place, comprising:

• 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, wherein
• the stator includes a plurality of coils made of a conductive wire and arranged to generate magnetic fields,
• the circuit board is provided with wiring lines electrically connected to the coils,
• the wiring lines include output-side land portions electrically connected to first ends of the coils, 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 or an external circuit board, 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, and
• each of the output-side wiring portions has a width greater than a width of the connection-side wiring portion.
