PROBLEM TO BE SOLVED: To provide communication equipment for efficiently radiating heat to the outside of a case body even in a tightly sealing case body. SOLUTION: The communication equipment having the case body 30 for tightly sealing and housing a printed wiring board 20 loaded with a heat generating componen comprises: a metallic heat radiation plate 10 installed parallelly to the printed wiring board, provided with a screw hole on a position corresponding to the heat generating component and attached to the case body; metallic heat radiation screws 11 screwed to the screw holes and screwed in matched with the height of the heat generating component; a heat radiation sheet 12 inserted between the heat generating component and the heat radiation screw so as to reduce heat resistance; and the heat radiation sheet 13 inserted between the heat radiation plate and the case body so as to reduce the heat resistance. The heat radiation plate is provided with an almost vertically bent end part and the end part is attached through the heat radiation sheet 13 to the inner surface of the case body almost vertically to the board.
