Solid catalyst component for olefin polymerization

A solid catalyst component for olefin polymerization comprising a hydrocarbon-insoluble product (III) obtained by reacting (A) a silicon compound selected from the group consisting of (1) halogen-containing silicon compounds, (2) silicon compounds having a monomeric unit (wherein R1 and R2 may be the same or different, R1 represents an alkyl, aryl, cycloalkyl, alkoxy, or aryloxy group, or a hydrogen atom, and R2 represents an alkyl, aryl, or cycloalkyl group or a hydrogen or halogen atom) and a polymerization degree of 2 to 10,000, (3) silanols of the general formula Rl3 Si(OH)4-l (wherein R3 represents an alkyl, aryl, or cycloalkyl group or a hydrogen atom, and l is 1, 2 or 3) or condensation products thereof, (4) silicon compounds represented by the general formula Rm4Si(OR5)4-m (wherein R4 represents n alkyl, aryl, cycloalkyl, or alkenyl group or a hydrogen atom, R5 represents an alkyl or aryl group or a fatty acid moiety, and m is 1, 2 or 3), and (5) silicon compounds or polymers thereof represented by the general formula [SiOa(OR6)b]n (wherein R6 represents an alkyl, cycloalkyl, aralkyl or aryl group or a fatty acid moiety, and a and b are each a number defined by the formula 0
