The present invention addresses a problem of providing a lipase derived from a microorganism that is specific for short-chain to medium-chain fatty acids. A modified lipase is obtained by making a substitution in the amino acid sequence of a Candida cylindracea derived lipase, wherein the substitution is (1) a substitution of asparagine for an amino acid corresponding to the amino acid at position 428 in the amino acid sequence set forth in SEQ ID NO: 1； or (2) a substitution of phenylalanine, methionine, or isoleucine for an amino acid corresponding to the amino acid at position 429 in the amino acid sequence set forth in SEQ ID NO: 1.
