PROBLEM TO BE SOLVED: To obtain an asymmetrically substituted fluorene compound which can present a new polymerization site around the central metal in a polymerization reaction, especially when derived to a metallocene complex. SOLUTION: The fluorene compound is expressed by formula (1), wherein the figures express the sites of substitution in the fluorene; R<SP>1</SP>expresses a halogen atom, a substituted or nonsubstituted 1-20C alkyl; a substituted or nonsubstituted 6-20C aryl; a substituted or nonsubstituted 7-20C aralkyl; a substituted or nonsubstituted 1-20C alkoxy; a substituted or nonsubstituted 6-20C aryloxy; a substituted or nonsubstituted 7-20C aralkyloxy; a silyl group substituted with a substituted or nonsubstituted 1-20C hydrocarbon group or an amino group substituted with a substituted or nonsubstituted 1-20C hydrocarbon group; A expresses an alicyclic structure integrally formed with the 6 and 7 sites of the fluorene.
