Abstract
A motor includes a rotor including a shaft centered on a vertically extending center axis, a stator radially opposite to the rotor and including coils, a bearing supporting the shaft, and a bus bar unit on an upper side in an axial direction of the stator. The bus bar unit includes bus bars including a terminal portion connected to a lead wire drawn out from the coil and a bus bar holder holding the bus bars. The terminal portion includes a slit which extends axially downward and into which the lead wire is fitted. The width of the slit is narrower than the diameter of the lead wire.
