Abstract: The rotating electrical machine of the present invention includes a stator coil obtained by curing the impregnating resin injected into the whole stator coil unit after an electrically insulated coil unit with a mica tape having been wrapped around a conductor is slotted into stator iron core slots via a slot liner. The high-heat-resistance resin component of the slot liner contains at least an epoxy resin having 3 or more epoxy groups. The high-heat-resistance resin component of the mica tape contains at least an alicyclic epoxy resin. The impregnating resin contains a bifunctional epoxy resin, and an acid curing agent having one acid anhydride skeleton. With the impregnating resin, the high-heat-resistance resin components of the slot liner and the mica tape form a liner cured portion and a mica insulating layer portion as an integral unit of different resin compositions inside the slot.
