Abstract
A production method for a stator involves forming leg parts of rectangular wire coils such that the leg part that is on one side in the circumferential direction of a stator core is longer in the axial direction of the stator core than the leg part that is on the other side in the circumferential direction. At each layer of every slot, the leg part on the one side of one rectangular wire coil is laid on the outside in the radial direction of the leg part on the other side of another rectangular wire coil. A second jig is pressed against the plurality of rectangular wire coils from one side in the axial direction toward the other side in the axial direction. As a result of this pressing, only the tip of the leg part on the one side of each layer is pressed against a respective step of a stepped part of a first jig.
