PROBLEM TO BE SOLVED: To provide a co-generation apparatus capable of carrying out next operation without complicating the constitution of the apparatus even in a blocked state of an exhaust passage of a heat exchanger due to freezing of condensed water of exhaust gas of an internal combustion engine. SOLUTION: The co-generation apparatus includes a heat exchanger (an exhaust heat exchanger) 30 connected to the internal combustion engine to exchange heat between exhaust gas heat and cooling water of the internal combustion engine to raise temperature. The heat exchanger 30 includes an intake port 30a taking in exhaust gas output from the internal combustion engine; first and second exhaust ports 30b, 30c exhausting the taken-in exhaust gas; and a pressure valve (a pressure release valve) 80 arranged in the second exhaust port 30c and opened when the pressure of the taken-in exhaust gas is a predetermined value or higher.
