To provide a novel fluorine-containing alkyne compound having perfluoroalkylene, perfluoroalkyl or perfluoropolyether as a main chain structure and a method for producing the same.SOLUTION: This invention provides a fluorine-containing alkyne compound represented by general formula (1). In general formula (1), A and B independently represent a linear or branched aliphatic saturated hydrocarbon group or phenylene group, and Rfis a perfluoroalkylene group or a divalent perfluoropolyether group. In general formula (1), preferably A is at least one of a C1-10 linear aliphatic saturated hydrocarbon group, a C1-10 branched aliphatic saturated hydrocarbon group, an ortho-substituted phenylene group, a meta-substituted phenylene group, and a para-substituted phenylene group, and B is a C1-10 linear aliphatic saturated hydrocarbon group or a C1-10 branched aliphatic saturated hydrocarbon group.SELECTED DRAWING: None 【課題】パーフルオロアルキレン、パーフルオロアルキル又はパーフルオロポリエーテルを主鎖構造とする新規含フッ素アルキン化合物及びそれらの製造方法を提供する。【解決手段】一般式（１）で表される含フッ素アルキン化合物。一般式（１）中、Ａ及びＢは、互いに独立して、直鎖型若しくは分岐型の脂肪族飽和炭化水素基又はフェニレン基であり、Ｒｆ1はパーフルオロアルキレン基又は２価のパーフルオロポリエーテル基である。一般式（１）において、Ａは、炭素数１〜１０の直鎖型脂肪族飽和炭化水素基、炭素数１〜１０の分岐型脂肪族飽和炭化水素基、オルト置換のフェニレン基、メタ置換のフェニレン基、パラ置換のフェニレン基のいずれか一つであり、Ｂは、炭素数１〜１０の直鎖型脂肪族飽和炭化水素基又は炭素数１〜１０の分岐型脂肪族飽和炭化水素基であることが好ましい。【選択図】なし
