(57) [Abstract] [Problem] Applicable to suspension polymerization and gas phase polymerization, Provided is an olefin polymerization catalyst capable of obtaining an olefin polymer having high polymerization activity and excellent particle properties. SOLUTION: (A) a particulate carrier, (B) a transition metal compound of Groups 8 to 10 of the periodic table represented by the following formula, and (C) (C-1) Organoaluminumoxy compound, (C-2) Alkylboronic acid derivative, (C-3) Lewis acid or at least one compound selected from ionic compounds, and (D) Organometallic, if necessary Olefin polymerization catalyst formed by prepolymerizing an olefin into a catalyst component consisting of a compound (M is a transition metal atom of Groups 8 to 10 of the periodic table, X 1 and X 2 are nitrogen atoms or phosphorus atoms, R 1 and R 2 are hydrogen atoms or hydrocarbon groups, and R 6 and R 7 are hydrogen atoms or carbon atoms. Hydrogen group, R 4 and R 5 are halogen atom or hydrocarbon group) |
