PROBLEM TO BE SOLVED: To provide a cooling device having suitable cooling efficiency with respect to different two cooling systems, and able to be housed in a limited space. SOLUTION: A hybrid vehicle is equipped with an engine 100 and a driving motor 102 as a prime mover, and is constituted to travel by driving force of one of or both of them in accordance with predetermined driving conditions. A radiator for cooling the engine whereby cooling water is circulated between itself and the engine 100 is provided as a cooling device for the engine 100, and a radiator for cooling a strong electricity system whereby the cooling water is circulated between itself and strong electricity parts is provided as a cooling device of the strong electricity system including the driving motor 102, a power supply 112 for driving the driving motor, and a power generating motor 104. The radiator for cooling the engine and the radiator for cooling the strong electricity system are arranged so that respective cores are arranged in parallel and are directed to an advancing direction of the vehicle. The front surface projection area of a cooling water passage of the radiator arranged in a front part is smaller than the front surface projection area of a cooling water passage of the radiator arranged in the rear part.
