The motor unit includes: a motor including a rotor having a shaft rotatable about a rotation axis and a stator surrounding the rotor from a radial outer side; a housing that accommodates the motor; a bearing that is fixed to the housing and that rotatably supports the shaft; a resolver having a resolver rotor fixed to the shaft and a resolver stator fixed to the housing; and a contact member which has conductivity, is fixed to the housing, and is in contact with a contacted portion provided at an end portion on one side in the axial direction of the shaft. The housing has an accommodating space for accommodating the contacted part of the shaft. The contact member and the resolver are arranged in the housing space so as to be aligned in the direction of the rotation axis.
