A motor unit, which is an example of an embodiment, includes a motor including a motor shaft, a rotor fixed to the motor shaft, and a stator, and a control board, the control board being disposed with at least a part of the control board overlapping the motor when viewed in a motor axial direction. A sensor that detects a magnetic field of the motor shaft, the rotor, or a rotating body rotating together with the motor shaft, and a control element that controls the motor using detection information of the sensor, are mounted on the control board. The control board includes a signal line that connects the sensor and the control element. The signal line includes an arcuate wiring section bent to be convex in a radial direction outer side of a circle centering on a shaft core of the motor shaft.
