PROBLEM TO BE SOLVED: To manufacture a highly reliable rotating electric machine by reducing a risk that there may be generated a short-circuit or a partial discharge between conductors which constitute a coil of each phase. SOLUTION: After a coil winding process (S101) for winding the coil of each phase to a stator core, an insulation test process between in-phase parallel conductors is performed (S104) via a coil-end forming process (S102) and a first lacing process (S103). After that, after performing a three-phase lead line caulking process (S105) for connecting power supply terminals, a neutral point caulking process (S106) for forming a neutral point, a neutral point insulation process (S107) for covering the neutral point with an insulation tape, and a second lacing process (S108) for tightly binding the neutral point by a thread, a stator which is manufactured via an integrated insulation test/inspection process (S109), a varnish impregnation process (S110), and a stator inspection (S111) for inspecting the state of the stator is combined with a rotor, thus manufacturing the rotating electric machine.
