A stator core includes a yoke member and a teeth member. The yoke member is in an annular shape. The teeth member includes teeth and connecting portions. The teeth are projected from the yoke member radially inward. The teeth are formed of a steel plate stacked along a circumferential direction. At least one of the connecting portions connects a part of a tip end of one of the teeth in an axial direction with a part of a tip end of an other of the teeth in the axial direction. The one of the teeth and the other of the teeth are adjacent to each other in the circumferential direction.
