The gas turbine fuel gas filling apparatus comprises a fuel main valve, a fuel valve, an inert gas purge valve, and a pressure detector for detecting a pressure in the fuel line. The fuel main valve is gradually opened, and fixed to a valve opening at a time when a predetermined first pressure condition is established. Pressure is measured after lapse of a predetermined time. The fuel main valve is gradually opened until a second pressure condition is established. Pressure is measured upon a completion of gas-filling. With establishment of a third pressure condition, the inert purge relief valve is closed. With establishment of a fourth pressure condition, the fuel main valve is fully opened.
