This stator is provided with an annular yoke comprising a plurality of recesses disposed at equal intervals in the inner periphery, and with teeth which, in a state before being fitted and fixed in the recesses, are concentratedly wound in series with winding wire of the same phase for each AC phase group, and which, after winding, are fitted and fixed in the recesses alternately such that different phase groups are adjacent to one another. Further, this method is for manufacturing a stator which comprises winding wire wound around the stator core formed having an annular yoke comprising a plurality of recesses disposed at equal intervals in the inner periphery, and teeth fitted and fixed in the recesses, wherein said method involves: a step in which, in a state before the teeth are fitted and fixed in the recesses, teeth of each AC phase group are concentratedly wound with winding wire of the same phase in series; and a step in which, after the winding, the teeth are fitted and fixed in the recesses alternat
