PROBLEM TO BE SOLVED: To provide a gas turbine plant capable of sufficiently uniformly cooling inlet air by uniformly including liquid-drops in inlet air, even if the constitution on an inlet side of a compressor is any constitution, and attaining improvement of an output of the gas turbine plant. SOLUTION: In this gas turbine plant in which an intake chamber 12 provided on a gas intake side of the compressor and a liquid-drop spray device which is arranged at the inside of the intake chamber 12 and sprays liquid-drops to inlet gas of the compressor are provided, liquid-drops are mixed with inlet gas of the compressor and inlet gas is cooled, the liquid-drop spray device is provided with a liquid-drop spray nozzle pipe 51 spread within substantially perpendicular cross section in an intake flow passage within the intake chamber 12 and a plurality of liquid-drop spray nozzles 52 provided at prescribed intervals in the liquid-drop spray nozzle pipe 51, and the arrangement distribution of the liquid-drop spray nozzles 52 is made so as to be dense at a portion where gas flow velocity is fast within cross section of the intake chamber 12 and so as to be non-dense at a portion where gas flow velocity is slow.
