PROBLEM TO BE SOLVED: To provide a stacked stator core, each iron core piece of which is bonded with ample strength and its strains that arise are small within a range that causes no harm in usage. SOLUTION: With a plurality of segmented iron cores 15-17, formed by caulking and stacking the iron core pieces 11 consisting of a plurality of thin plate materials, the iron core pieces 11 of the portion, except for the upper portion 21 of the segmented iron core 15 positioned at the topmost portion and the lower portion 22 of the segmented iron core 17 positioned at the bottommost portion are bonded by welding to integrate all the segmented iron cores 15-17.
