An olefin polymerization is conducted in the presence of a catalyst comprising a solid catalyst component and an organometallic compound, said solid catalyst component being prepared by reacting the following components [I], [II] and [III], with one another: [I] a reaction product obtained by reacting the following components (1), (2) and (3) with one another in the presence of a compound represented by the general formula R2OH where R2 is a hydrocarbon group having 1 to 20 carbon atoms: (1) a silicon oxide and/or an aluminum oxide (2) a reaction product obtained by the reaction of a magnesium halide and a compound represented by the general formula Me(OR)n X z-n where Me represents an element of Groups I to IV in the Periodic Table, z represents the valence of the element Me, n is 0<n~z, X is a halogen atom and R is a hydrocarbon group having 1 to 20 carbon atoms, and (3) a titanium compound represented by the general formula Ti(OR1)m X4-m; where R1 is,a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom and m is 0~m~4. [II] an organoaluminum compound represented by the general formula Al(OR3)p R4q X3-(p+q) where R3 and R4, which may be the same or different, are each independently a hydrocarbon group having 1 to 24 carbon atoms, X is a halogen atom or a hydrogen atom, p and q are 0~p<3 and 0~q~3, respectively, provided 0<p+q~3; and [III] a silicon compound having at least one Si-N-C bond.
