1. A motor comprising:
a stator including a stator core and a coil, the stator core having a plurality of teeth arranged at intervals in a circumferential direction, the coil being formed of an electrically-conductive winding wound around the teeth;
a rotor having magnets arranged in radial opposition to the stator core and at intervals in the circumferential direction, the rotor being configured to rotate upon supply of electric current to the coil; and
a sensor arranged in a circumferentially intermediate area between a circumferentially-adjacent pair of the teeth in an axial view, the sensor being configured to detect magnetism of the magnets, wherein:
the sensor is mounted to a circuit board that radially extends so that a thickness direction of the circuit board coincides with an axial direction;
the circuit board is shaped such that the coil wound around the teeth of the stator core is visible when the circuit board is viewed along the axial direction; and
the circuit board is arranged to face at least part of the coil in the circumferential direction.
