To provide a method for industrially efficiently producing optically active haloalcohols which are intermediates of an optically active ketene dithioacetal derivative useful as an antifungal agent.

The method for producing the optically active haloalcohols represented by general formula (I) (wherein, * represents an asymmetric carbon; R represents a hydrogen atom or a halogen atom; and X represents a halogen atom) comprises subjecting an optically active half esters of phthalic acid represented by general formula (II) (wherein, *, R and X are the same as the above) or a salt thereof to the aminolysis by using amines.
