Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a chiral dopant having large HTP and expressing shortening of the pitch of an induced helix depending on a temperature rise. SOLUTION: This optically active compound is expressed by general formula (1) [wherein (m) and (n) each express an integer of 4-8; A is selected from a group of structural formulae consisting of -Ph-COO-, -COO-Ph-, and -OOC-Np- COO- (-Ph- expresses 1,4-phenylene; -Np- expresses 2,6-naphthylene); C* expresses an asymmetric carbon].
