1. A rotating electric machine stator manufacturing method for forming a resin film on coil film peeled-off portions of a rotating electric machine stator by liquid resin material, the method comprising:
an immersion process of immersing the coil film peeled-off portions of the rotating electric machine stator in the liquid resin material; and
a heat curing process of heat curing the liquid resin material after release of the immersing to form the resin film, wherein
the liquid resin material has thixotropy; and
the immersion process includes a process of immersing the coil film peeled-off portions in the liquid resin material without heating and causing the rotating electric machine stator to move in a direction other than a vertical direction at least once at least while the coil film peeled-off portions are immersed in the liquid resin material.
