PROBLEM TO BE SOLVED: To provide a metallocene complex that incorporates ethylene and an α-olefin as comonomers with better efficiency than conventional metallocene catalysts and gives a polymerized high-molecular weight rubber component in copolymerization of olefins including propylene as a monomer, and produces homopolypropylene having a high melting point in homopolymerization of propylene, and to provide an olefin polymerization method using the same.SOLUTION: The metallocene catalyst is represented by general formula [I], which has a cyclic structure between the 5- and 6-positions of the indenyl ring and has an optionally substituted furyl or thienyl group at the 2-position of the indenyl ring. The olefin polymerization catalyst comprises the metallocene complex. The olefin polymerization method comprises polymerizing or copolymerizing olefins by using the olefin polymerization catalyst. |
