PROBLEM TO BE SOLVED: To radiate effectively the heat inside a communication apparatus without increasing the dimensions of its housing and the radiator thereof, by providing solar batteries on its sun shades, and by providing on its one sun shade fans connected electrically with the solar battries. SOLUTION: Sun-shades 21 are so provided by joints 22 having high thermal conductivities on the side surfaces and top surface of a housing case 11 as to cover the surfaces therewith. Also, on one side surface of the housing case 11, a housing radiator portion 12 is provided to provide water resistant fans 3 on a sun shade 2 opposed to the one side surface of the housing case 11 whereon the housing radiator portion 12 is provided, and on the sun shades 21, solar battery panels are provided. Further, the water resistant fans 3 are connected electrically with the solar battery panels to operate the water resistant fans 3 by the power generated through the solar battery panels. Thereby, the heat inside a communication apparatus can be radiated efficiently without increasing the dimensions of its housing case 11 and the radiator 12 thereof.
