Abstract
A stator is formed by laminating electrical steel sheets punched into a predetermined shape. The stator includes split cores that are punched out from the electrical steel sheets to have an annular shape. A first group of the split cores adjacent to each other in the circumferential direction have the same rolling direction, and a second group of the split cores adjacent to each other in the circumferential direction have different rolling directions.
