The objective of the present invention is to provide a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative with high yield and high optical purity using a safe material available at low cost. In addition, the objective of the present invention is to provide a method for safely-obtaining an optically active vinylcyclopropaneamino acid with high optical purity at low cost. The problems can be solved by a method for obtaining an optically active vinylcyclopropanecarboxylic acid derivative, which method contains the step of reacting a racemic vinylcyclopropanecarboxylic acid derivative with an optically active amine compound, to obtain a diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative - amine compound. In addition, it is possible to obtain a vinylcyclopropaneamino acid by deriving the vinylcyclopropaneamino acid from thus obtained diastereomer salt of optically active vinylcyclopropanecarboxylic acid derivative - amine compound.
