A stator includes a cylindrical shaft extending in an axial direction, annular portions positioned side by side in the axial direction radially outside the shaft and extending in a radial direction, pole teeth extending in the axial direction from a radially outer end portion of each of the annular portions, and one or more coils between the annular portions adjacent to each other in the axial direction and wound around the shaft. The shaft includes at least one slit recessed radially inward from an outer peripheral surface of the shaft and extending along the axial direction. A portion of the at least one slit is radially inside the annular portion. A lead wire of the coil is accommodated in the at least one slit.
