Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a defrosting method and a defrosting device of a pre-cooling gas turbine system capable of minimizing increase of weight and capable of easily and efficiently defrosting without interrupting cooling while defrosting. SOLUTION: Frost adhering on a cooling surface is blown away to defrost by introducing part of high pressure air from a down stream side of a compressor 2 in the pre-cooling gas turbine system to a pre-cooling device 6 provided at an upstream side through an air duct line 8 and injecting and colliding the high pressure air from a nozzle 7 to the cooling surface of the pre-cooling device 6 at a high speed.
