PROBLEM TO BE SOLVED: To provide a cooling system where a VCS(vapor cycle system) is not used in an antenna device which is loaded on an aircraft and which requires cooling to a temperature lower than the temperature of a heat discharge destination. SOLUTION: A skin 2 corresponds to the outer wall of an aircraft and it also constitutes the outer wall of an antenna device with the heat radiation board of the antenna device. A module 4 generates heat for amplifying a signal and requires cooling to a temperature not more than a prescribed temperature. An antenna element 5 radiates the signal amplified by the module 4 into space and is connected to the module 4. Peltier plates 6 are constituted of a semiconductor whose thermoelectric conversion efficiency is large and can obtain a cooling effect by supplying power and they are installed on both ends of the antenna device. The heat generation (heating) side of the Peltier plates 6 are fixed to the skins 2 constituting the outer walls of the antenna device. A base plate 7 mounts two modules 4 on the upper and lower surfaces and both ends of it are fixed to the heat absorbing (cooling) sides of the Pertier plates 6.
