Provided is a method capable of industrially producing optically active (S)-7-hydroxy-6-methylheptan-2-one and its precursor simply and efficiently. The production method, allows a R-body preferentially hydrolyzable Aspergillus microorganism-derived esterase to act on a 2-methyl-6-oxoheptanoate (II), to produce an optically active (S)-2-methyl-6-oxoheptanoate (III).
