PROBLEM TO BE SOLVED: To provide a vehicle-mounted cooling device capable of obtaining a sufficient cooling performance while integrating a case accommodating an electric system. The present invention relates to a vehicle-mounted cooling device (1), including a case (4a, 6a, 8a) and a rotary electric machine (1) housed in a first space (30c) inside the case (4a, 6a, 8a). 4), the power converters (8b, 8c) housed in the second space (28c) inside the case, and the rotating electric machine in the first space using the first cooling liquid. A first cooling mechanism (18) for cooling, a second cooling mechanism (16) for cooling the power conversion device in the second space using a second cooling liquid, a rotating electric machine and power conversion. A conductor (24, 26) extending inside the case so as to connect the devices, and a seal member (34) for sealing between the first space and the second space, the seal member comprising: It is characterized in that mixing of the first cooling liquid in the first space and the second cooling liquid in the second space is suppressed.
