PROBLEM TO BE SOLVED: To improve the efficiency of a gas turbine device. SOLUTION: When gas, such as air, enters the compressor C 10 of a gas turbine device 100 (state 1), the gas is brought into a high temperature gas by a combustor B 102 (state 3) and directed to a turbine T 103. Another turbine T 104 is arranged in the rear of the turbine T 103 in which air in the state 3 flows and the air enters a first heat-exchanger Hx 105 (a state 4) and compressed by a compressor C 109 (a state 5). Thereafter, the gas flows through the heat-exchanger Hx 106 of an intermediate cooling part 151, a compressor C 110, a heat-exchanger Hx 107, a compressor C 111, and a heat-exchanger Hx 108 (states 6-11) and discharged from a compressor C 112 (a state 12).
