Abstract
A metallocene complex by which high uptake efficiency of ethylene and/or α-olefin can be obtained compared with the conventional metallocene catalyst, and robber component having high molecular weight can be polymerized, and polymerization method of olefin. Metallocene complex (metallocene complex having furyl or thienyl group in which substituent exists at 5-position of indenyl ring, and substituent may exist at 2-position of indenyl ring, and the like) represented by the general formula [II], the catalyst for olefin polymerization characterized by comprising said metallocene complex, and polymerization method of olefin characterized that polymerization or copolymerization of olefin is carried out using said polymerization catalyst for olefin, and the like.
