Abstract

A stator is assembled by stacking, in the axial direction, a plurality of magnetic steel sheets having tooth portions. The steel sheets include connected tooth steel sheets in which the inner-circumferential-side end portions of the tooth portions are connected via connection portions in an annular shape along the circumferential direction, and non-connected tooth steel sheets which are separated from each other with the tooth portions not connected to each other. The connected tooth steel sheets and the non-connected tooth steel sheets are joined to each other in the axial direction via swage portions provided in the tooth portions. The thickness of each connection portion is smaller than the thickness of the other part of each steel sheet.
