A stator core of a cooling apparatus includes: a back yoke having a cylindrical shape; a plurality of tooth portions that protrude along a radial direction from the back yoke; a plurality of slots that are formed between the tooth portions adjacent in a circumferential direction; a cooling path which is provided on the back yoke along the circumferential direction so as not to be in communication with the slot and in which a refrigerant flows; and a refrigerant supply port that is formed on the back yoke and supplies the refrigerant to the cooling path, in which the cooling path is configured to be divided into at least two portions in the circumferential direction, and the refrigerant supply port is formed on each cooling path.
