PROBLEM TO BE SOLVED: To provide a cooling device that is improved in cooling capability while reducing pressure loss of a cooling medium. SOLUTION: Partition plates 20-1 and 20-2 connecting upstream cooling fins 14 and downstream cooling fins 15 form communication flow passages 18 making upstream cooling medium flow passages 16 and downstream cooling medium flow passages 17 communicate with each other between a reverse surface 12b of a cooling plate 12 and the partition plates 20-1 and 20-2. A pair of partition plates 20-1 and 20-2 which gradually increase in interval from an upstream cooling fin 14 to a downstream cooling fin 15 is coupled to the upstream cooling fin 14, and the pair of partition plates 20-1 and 20-2 which gradually increase in interval from a downstream cooling fin 15 to an upstream cooling fin 14 is coupled to the downstream cooling fin 15. The upstream cooling fin 14 to which the pair of partition plates 20-1 and 20-2 are coupled gradually decreases in thickness from the upstream side to the downstream side of a cooling medium flow.
