Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a bi-nuclear metallocene catalyst capable or preparing a single peak or twin peaks olefin polymer by using a single reaction vessel, and improving he reactivity, conversion rate and up take rate of a diene. SOLUTION: This bi-nuclear metallocene catalyst for polymerizing an olefin is expressed by formula I[R3 to R6 are each a (substituted) cyclopentadienyl; M is an element of 4th group; M1 and M2 are each a transition element in 3rd, 4th and 5th groups; X is H, a 1-20C hydrocarbyl, a halogen, a 1-20C alkoxy, a 1-20C oxyallyl, NH2 or the like; L is a neutral ligand selected from an amine, a-phosphorus compound, ether and thioether compounds; (i) is 1-3; (j) is 0 or 1; (i+j)
