A laminated core, including a plurality of continuous segment core sheets spirally wound and laminated in layers while connecting portions of a core sheet band connecting the adjacent segment core sheets are bent, the core sheet band provided with a plurality of magnetic pole sections on radially inward sides or radially outward sides of yoke sections in the segment core sheets, radially inward or outward ends of the segment core sheets being aligned with one another, the connecting portions located in outer peripheral areas of the segment core sheets, the laminated core comprising: concave cutouts formed on a radially outward side of the connecting portions, the concave cutouts accommodating radially expanded parts within an outer circle of the laminated core, the radially expanded parts formed in the connecting portions radially outward at the bending of the connecting portions when, at the time of arching of the connecting portion, the outer peripheral area thereof is stretched in the circumferential direction to become thinner; interior cutouts formed on a radially inward side of the connecting portions, the interior cutouts defining bent positions of the connecting portions; and depressed receptacles (16, 17) respectively formed in between each of the adjacent magnetic pole sections in the segment core sheets, the depressed receptacles being on a top side and a bottom side of a radially outward area of the segment core sheets except for the connecting portions, the connecting portions in the adjacent layers being circumferentially displaced relative to one another, the depressed receptacles (16, 17) receiving thickness-direction expanded parts formed in the connecting portions in a thickness direction thereof at the bending of the connecting portions when, at the time of arching of the connecting portion, the inner peripheral area thereof is shrunk in the circumferential direction. concave cutouts formed on a radially outward side of the connecting portions, the concave cutouts accommodating radially expanded parts within an outer circle of the laminated core, the radially expanded parts formed in the connecting portions radially outward at the bending of the connecting portions when, at the time of arching of the connecting portion, the outer peripheral area thereof is stretched in the circumferential direction to become thinner; interior cutouts formed on a radially inward side of the connecting portions, the interior cutouts defining bent positions of the connecting portions; and depressed receptacles (16, 17) respectively formed in between each of the adjacent magnetic pole sections in the segment core sheets, the depressed receptacles being on a top side and a bottom side of a radially outward area of the segment core sheets except for the connecting portions, the connecting portions in the adjacent layers being circumferentially displaced relative to one another, the depressed receptacles (16, 17) receiving thickness-direction expanded parts formed in the connecting portions in a thickness direction thereof at the bending of the connecting portions when, at the time of arching of the connecting portion, the inner peripheral area thereof is shrunk in the circumferential direction.
