PROBLEM TO BE SOLVED: To provide a working gas circulation type engine inhibiting supply of moisture into a combustion chamber. SOLUTION: The working gas circulation type engine includes: the combustion chamber 11 in which an oxidant, fuel generating steam through combustion with the oxidant and a working gas having a specific heat ratio higher than air are supplied and the working gas is expandable with the combustion of the fuel and which can exhaust the steam and the working gas after the combustion of the fuel; a circulation path 20 capable of circulating gas containing the working gas from an exhaust side of the combustion chamber 11 to an intake side and supplying the same to the combustion chamber 11 again; and a removal device 50 provided in the circulation path 20 and removing the steam contained in the gas circulating in the circulation path 20. The circulation path 20 has a hollow 22 capable of storing moisture remaining in the gas circulating between the removal device 50 to the intake side of the combustion chamber 11 with respect to the circulation direction of the circulating gas by means of the own weight.
