Stator core

A stator core for a rotary electric machine and having a cylindrical shape centered on a central axis, the stator core comprising:

• a plurality of core blocks aligned in an axial direction parallel to the central axis, wherein each of the plurality of core blocks comprises a plurality of electromagnetic steel plates stacked in the axial direction and integrated by being crimped to each other;
• and
• a plurality of welded portions arranged on an outer peripheral surface of the stator core, wherein each of the plurality of welded portions extends in the axial direction,
• wherein the plurality of core blocks includes a first core block located farthermost on one side of the axial direction and a second core block located farthermost on another side of the axial direction, and
• a total length of the plurality of welded portions on the outer peripheral surface of the second core block is shorter than a total length of the plurality of welded portions on the outer peripheral surface of the first core block.
