Abstract
The unit coil is formed by: bending the coil end portions of the intermediate body such that, in a layer in which a length in an axial direction between the coil end portions is large, positions of the coil end portions projecting furthest from the accommodation portions in the axial direction move away from positions of the accommodation portions in the stacking direction, compared to the previous state; and aligning the positions, in the axial direction, of the coil end portions at an inner side of the annular shape, for each of the layers.
