Beschreibung
Zusammenfassung:	A hollow metal part is used as a pipe component for a refrigerant flow path of a rotating electrical machine adapted to cool a stator coil with a refrigerant. The rotating electrical machine includes a connection arm that couples the stator coil and a power supply terminal at a stator coil end portion of the stator coil, and an insulating hose that is coupled to the stator coil and the connection arm through a first hollow metal part in order to supply the refrigerant to the stator coil and the connection arm. The first hollow metal part is formed integrally by joining a part formed of stainless steel to a part made of oxygen-free copper.
