[Problem to be solved] To provide a rotating electrical machine capable of preventing a refrigerant leaked from a refrigerant flow
path from entering the inside of a frame even when the refrigerant leaks from an opening leading to the refrigerant flow path.
[Solution] A rotating electrical machine according to an embodiment includes a rotor rotatable around a rotation shaft, a stator
arranged to face the rotor, and a frame 2 which accommodates the rotor and the stator and in which a refrigerant flow path 22 is
formed in a sidewall 20. The frame includes a through hole 26 that penetrates from the refrigerant flow path 22 to an outer
