PROBLEM TO BE SOLVED: To provide a combustor suppressing an increase in manufacturing cost and weight when reducing the size and effectively regenerating and using the heat of exhaust gas, and to provide a gas turbine engine. SOLUTION: The combustor 1 includes an approximately cylindrical casing 2, a liner 3 arranged inside the casing 2 in an approximately concentric manner, and an exhaust pipe 4 arranged inside the liner 3 in an approximately concentric manner. It further includes a compressed air flow path 5 formed outside the liner 3, and a combustion chamber 6 formed inside the liner 3. Herein, compressed air flowing in the compressed air flow path 5 is opposed to combustion gas generated in the combustion chamber 6. The casing 2 and the exhaust pipe 4 are joined to each other in a heat transferable manner. The casing 2 uses a raw material having a higher heat conductivity than that of the exhaust pipe 4.
