A novel, optically active alkenylphosphinic acid ester having chirality on a phosphorus atom; and a simple process for producing the ester. An optically active, hydrogen phosphinic acid ester is reacted with an acetylene compound in the presence of a catalyst containing a metal of group 9 or 10 of the periodic table to thereby obtain a novel, optically active alkenylphosphinic acid ester which has chirality on a phosphorus atom and is represented by the following general formula [1] and/or [2].
