A stator of a rotating electric machine includes a stator core provided with a plurality of slots along a circumferential direction, coils of a plurality of phases distributedly wound around the stator core via the plurality of slots, and an insulating paper disposed between the slot and the coil. The insulating paper has an adhesive portion which fixes the coil to the stator core and a part of the coil of each phase is fixed to the stator core by the adhesive portion.
