Provided is a novel fluorene derivative which is useful as a catalyst component for olefin polymerization, a transition metal compound containing the fluorene derivative as a part of ligand, a catalyst for olefin polymerization containing the transition metal compound, and a process for producing olefin polymer. The fluorene derivative is characterized by being represented by the following general formula [I]: wherein R 1 , R 2 , R 3 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , and R 14 are each selected from hydrogen, a hydrocarbon group, and a silicon-containing group, and may be the same as or different from each other, R 4 and R 13 are each selected from hydrogen, a hydrocarbon group, a silicon-containing group, a sulfur-containing group, an oxygen-containing group, a nitrogen-containing group, and a halogen-containing group, and may be the same as or different from each other, and adjacent substituents of R 1 to R 14 may be bonded to each other to form a ring, except that the case where R 4 and R 5 , and R 12 and R 13 are each bonded to each other to form a vinylene group. Also provided is a bridged metallocene compound having both of the skeleton and a cyclopentadiene skeleton.
