摘要： The rotating electrical machine (9) of the present invention includes a stator coil (7) obtained by curing the impregnating resin injected into the whole stator coil unit after an electrically insulated coil unit with a mica tape (4) having been wrapped around a conductor (3) 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 (4) form a liner cured portion and a mica insulating layer portion (4) as an integral unit of different resin compositions inside the slot.
