PROBLEM TO BE SOLVED: To provide a stator manufacturing device that circularizes divided cores with higher accuracy. SOLUTION: A pressurizing jig includes a cylindrical holding member in which the divided cores are arranged at the internal peripheral side and a plurality of axially penetrating insertion holes are formed, and a plurality of pressurizing pieces 52 which are inserted into the insertion holes respectively so as to be movable in the axial direction. Inside tapered faces 33, 41 and outside tapered faces 56, 57 are formed at the radial outside of the holding member at each pressurizing piece 52 and at the internal periphery of an operation jig. In the holding member, inside through-holes 55 are formed at positions corresponding to circumferential ends of the adjacent divided cores so as to penetrate the positions in the radial direction. In the operation jig 22, there are formed outside through-holes 35, 42 which are arranged on the same radial lines as those of the inside through-holes 55, penetrate in the radial direction, and enable welding to be performed from the outside. In the operation jig 22, there are formed fluid flow-in holes 38, 76 which communicate with the outside through-holes 35, 42, and can make inert gases G flow therein from the outside.
