PROBLEM TO BE SOLVED: To provide a radiator in which maximum air flow can be obtained without using a fan of large power or high speed rotation, desirable radiation effect can be improved and noise can be suppressed. SOLUTION: In the radiation device, a fan composed of a fan frame and an impeller which is freely rotatably disposed in the fan frame is arranged in a radiation means having a plurality of fins disposed in parallel. The impeller is formed of a hub and a plurality of blades installed along a periphery on an outer peripheral face of the hub. The fan frame includes a driving part where the impeller is freely rotatably installed and a supporting part which is arranged between the fan frame and the driving part, and which connect them, and the fan frame is installed so that the supporting part is in the same direction as the fins of the radiation means in parallel.
