Summary:An electrical rotary machine includes coils including element wires wound, and a core holding the coil, wherein spaces, both between the coils and the core, and between the adjacent element wires, are filled with a heat-conductive insulating resin. A method of manufacturing the electrical rotary machine includes a first step of impregnating the coils and filling the space between the adjacent element wires with the heat-conductive insulating resin, and a second step of impregnating the coils and the core and filling the space between the coils and the core with the heat-conductive insulating resin.
