A cooling structure for a stator configured with a cooling medium distributing member formed with a plurality of discharge openings, and a distributing path, wherein the distributing path has a plurality of chambers separated by a partition wall, and an inter-chamber communication passage that is formed in the partition wall and communicates between the adjacent chambers. The cooling medium distributing member includes at least one cooling medium distributing chamber that divides the distributing path to a plurality of inter-chamber communication passages, and also includes a plurality of discharge chambers. The plurality of inter-chamber communication passages formed in the partition wall are formed with a ratio of an opening width between the different inter-chamber communication passages set according to a ratio of a sum of opening cross-sectional areas of all of the cooling medium discharge openings which are located downstream of each of the inter-chamber communication passages.
