The present invention is a fluorohydrocarbon compound-filled gas container obtained by filling a gas container with a fluorohydrocarbon compound, the gas container being made of manganese steel, an amount of aluminum adhering to an inner surface of the gas container as measured by XPS analysis being 1 mol % or less, and the fluorohydrocarbon compound being a compound represented by C.sub.4H.sub.9F or C.sub.5H.sub.11F. The present invention provides a fluorohydrocarbon compound-filled gas container that is obtained by filling a gas container with a fluorohydrocarbon compound represented by C.sub.4H.sub.9F or C.sub.5H.sub.11F, and suppresses or reduces a decrease in the purity of the fluorohydrocarbon compound with which the gas container is filled.
