A motor stator of the invention is provided with a laminated stator core comprising a plurality of core pieces having teeth and linked by intermediate thin-wall portions. The thin-wall portions are bent to form the stator core into an annular shape with two ends of the stator core joined by welding, and slots are formed between adjoining pairs of the teeth. A welded portion of the stator core is not near a center line in a radial direction of any of the slots.
