    摘要： A solid catalyst component for olefin polymerization and a catalyst are disclosed that exhibit high catalytic activity when used for gas-phase polymerization, suppress rapid reactions in the initial stage of polymerization relative to the polymerization activity, and can produce a propylene polymer in high yield while maintaining high stereoregularity. The solid catalyst component for olefin polymerization includes magnesium, titanium, a halogen, and an internal electron donor, the solid catalyst component including an asymmetrical phthalic diester represented by the following general formula (1) in a molar ratio of 0.2 to 0.8 relative to the total content of the internal electron donor. R1k(C6H4-k)(COOR2)(COOR3)  (1) wherein R1 is an alkyl group or the like, R2 is a linear or branched alkyl group having 2 to 6 carbon atoms or an alkenyl group, R3 is a linear or branched alkyl group having 1 to 5 carbon atoms, the number of carbon atoms included in R3 being smaller than the number of carbon atoms included in R2, and k is an integer from 0 to 4 that indicates the number of substituents R1.
