PROBLEM TO BE SOLVED: To hold shielding cases which surround wireless boards in a housing with improved housing performance, maintainability and heat radiation performance. SOLUTION: Mating connectors 5 and heat transmitting protrusions 7 are formed on the end parts of shielding cases 1 which are thermally connected to housed wireless boards 3. A backboard 4 which has connectors 6 as holding parts and heat receiving protrusions 8 thermally connected to a housing 2 are placed in the housing 2. The connectors 5 are mated with the connectors 6 to hold the shielding cases 1 in the housing 2. The heat transmitting protrusions 7 are brought into contact with the heat receiving protrusions 8 for thermal connection. With this constitution, heat generated by heat generating components on the wireless boards 3 are transmitted to the housing 2 through the holding structure parts and radiated effectively, so that the housing performance and maintainability of the shielding cases 1 in the housing 2 can be improved.
