The invention provides a rotating electrical machine capable of being improved in rotating efficiency and efficiently cooling a coil. The rotating electrical machine is provided with: a stator havinga cylindrical stator core and a coil attached to the stator core; and a rotor (4) disposed on the inside in the radial direction of the stator, the rotor (4) being provided with: a rotor core (21) having a rotor internal flow path through which a cooling medium capable of cooling the axial center flows; and an end plate (23) disposed at an axial end of the rotor core (21). The end plate (23) has:a cooling medium flow hole (30) that communicates with the rotor internal flow path; and a cooling medium passage groove (31) that connects the cooling medium flow hole (30) and the outer peripheral edge (23a) of the end plate (23), and the radially outer groove width of the cooling medium passage groove (31) is equal to or less than the radially inner groove width when viewed from the axial direction. 本发明提供能够提高旋转电机的旋转效率，且
