PROBLEM TO BE SOLVED: To provide a cooling device of a connection conductor which efficiently cools the connection conductor, such as a bus bar, in which a temperature is increased by heat received from an electric device, such as a semiconductor element, and heat generated by the connection conductor itself, is small, and shortens a length of the connection conductor, and to provide an electric power conversion system using the cooling device of the connection conductor.SOLUTION: A cooling device of a connection conductor includes: a first connection conductor 2 which is led out from a first electric device 1 and has a first connection part 2a; a cooler 5; a heat transfer body 3 which is provided between the cooler and the first connection part and transfers heat of the first connection conductor to the cooler; and an electric insulative heat transfer material 4 disposed in one of areas between the heat transfer body and the cooler and between the heat transfer body and the first connection conductor. |
