PROBLEM TO BE SOLVED: To provide a cooling structure of an electrical box which efficiently cools a heating element.SOLUTION: A cooling structure of an electrical box 18 includes: a cooling plate 19 which is provided at the outer side of an electric box 18 housing a power element 50, is thermally connected with the power element 50, and cools the power element 50; and a coolant pipe 24 supplying a coolant from a coolant circuit 3 where the coolant circulates to the cooling plate 19. In the cooling structure of the electrical box, the cooling plate 19 includes inclination surface parts 19C, 19C which incline from a substantially center part to both side edge parts. Straight pipe parts 24A, 24A of the coolant pipe 24 are respectively disposed at the inclination surface parts 19C, 19C. The power element 50 is disposed in a region 55 corresponding to a space between the straight pipe parts 24A, 24A. |
