PROBLEM TO BE SOLVED: To provide an apparatus for effectively extracting gas dissolved in insulating oil which ensures the adequate circulation of insulation oil at the time of extracting the gas dissolved in the insulation oil of an oil-contained electrical apparatus in view of effectively extracting the gas dissolved in the oil. SOLUTION: An oil meter is arranged in a circulation path of the apparatus for extracting gas dissolved in oil for extracting the gas dissolved in the insulation oil, by supplying the insulation oil in the oil-contained electrical apparatus into an extraction vessel, and forming a pressure-evacuated space in the extraction vessel while the insulation oil is circulated into a circulation path; and the size of the pressure-evacuated space formed in the extraction vessel is controlled to a condition where an oil flow is detected in order to extract the gas dissolved in the insulation oil. Under this structure, the gas dissolved in the oil can be extracted easily, the variation of extraction work can be reduced and the gas dissolved in the oil can be extracted stably.
