PROBLEM TO BE SOLVED: To provide a cogeneration system and a power generator effectively recovering exhaust heat of exhaust gas of which effective use was difficult and further enhancing energy efficiency. SOLUTION: This cogeneration system is provided with a main power generator 100 generating electric power by using an internal combustion engine 110 as a drive source; hot water supply devices 20, 60 supplying hot water W heated by heat generated in the internal combustion engine 100 to a hot water demand 10; and an exhaust heat power generator 200 vaporizing a working medium M by heat of exhaust gas E of the internal combustion engine 110, generating electric power by the vaporized working medium M, condensing the working medium M that was used for the power generation by using hot water, and recovering the heat. The power generator is provided with a low-temperature exhaust heat power generator generating electric power using the hot water W as a heat source without supplying the hot water W to the hot water demand 10.
