Zusammenfassung:	PROBLEM TO BE SOLVED: To unfailingly prevent icing in the vicinity of an intake port of a gas turbine without degrading the efficiency of the gas turbine and incurring a cost increase in equipment and a burden on maintenance.SOLUTION: There is provided a gas turbine intake anti-icing device for use in a gas turbine power generating facility (1) equipped with a gas turbine (2) and a generator (20) coupled to the gas turbine to be rotationally driven for electric power generation. The device is provided with generator cooling mechanisms (21, 22, 23, 25) for taking in air from the outside to the generator to cool the generator. Besides, it is provided with an exhaust air supply passage (31) for connecting an exhaust passage (30) for air exhausted from the generator cooling mechanisms after cooling the generator to an air-intake passage (9) of the gas turbine so that the air exhausted from the generator cooling mechanisms can be supplied to the air-intake passage of the gas turbine via the exhaust air supply passage.
