PROBLEM TO BE SOLVED: To eliminate the need for a special heat insulating structure or heat resistant performance and to simplify wiring. SOLUTION: A communication apparatus 10 is configured by housing, in one case 11, a plurality of units including transmission/reception units 121, 122 having a high calorific value and branching filter units 131, 132 having a low calorific value. The branching filter unit 131 is then electrically connected to the transmission/reception unit 121 via a transmission signal line 161, and electrically connected to the transmission/reception unit 122 via a reception signal line 171. The branching filter unit 132 is electrically connected to the transmission/reception unit 122 via a transmission signal line 162 and electrically connected to the transmission/reception unit 121 via a reception signal line 172. Furthermore, the transmission/reception units 121, 122 are disposed laterally side by side, and the branching filter units 131, 132 are disposed longitudinally side by side between the transmission/reception unit 121 and the transmission/reception unit 122.
