PROBLEM TO BE SOLVED: To reduce manufacturing costs by surely cooling an outer cylinder portion by allowing the water to flow between the outer cylinder portion and an inner cylinder portion, so that inexpensive materials can be used for the outer cylinder portion. SOLUTION: This combustion device comprises a combustion chamber body 1 burning a burning material and exhausting a gas after combustion, a fluid supply portion 30 supplying the fluid to the combustion chamber body, and an outer chamber body 50 rotatably and drivably supporting the combustion chamber body 1. The combustion chamber body 1 is composed of the outer cylinder portion 10 and the inner cylinder portion 20, and the inner cylinder portion 20 is composed of heat-proof fluid composed of particles 21 meltable by heat in burning the burning material, and pressed to an outer cylinder portion 10 side by centrifugal force of the combustion chamber body 1 to form an inner wall of the combustion chamber body 1. The combustion device comprises a water supply portion 100 for supplying the water in such manner that it is pressed to the outer cylinder portion 10 side by centrifugal force in rotating the combustion chamber body 1 and flows down on an inner side face of the outer cylinder portion 10, and steam taking-out portions 110, 120 for taking out the steam generated when the water from the water supply portion 100 is evaporated in a process of flowing down on the inner face of the outer cylinder portion 10.
