PROBLEM TO BE SOLVED: To reduce risk of damaging a nozzle continuous with the downstream side by a collision of condensate, by reducing reduction in heat transmission capacity between high temperature gas and a cooling medium caused when water condenses on an inner wall of a combustion chamber, in a high temperature gas chamber. SOLUTION: Such a high temperature gas chamber has a combustion chamber wall body 15, and is constituted so that the combustion chamber wall body has inner surfaces 12' and 12" and a cooling flow passage 14 arranged outside the inner surfaces. The inner surfaces 12' and 12" of the combustion chamber wall body 15 facing a combustion chamber 4 are constituted so that at least its partial area avoids generation of liquid film-like condensation.
