A solid catalyst component for olefin polymerization includes a solid component obtained by causing a magnesium compound(a), a titanium halide compound(b), and an electron donor compound(c) to come in contact with each other, the titanium compound in an amount equivalent to a titanium content of 0.2 to 2.5 wt% in the solid catalyst component being washed away from the solid catalyst component by washing with heptane. A granular or spherical polymer that has high stereoregularity and a narrow particle size distribution can be obtained in high yield while suppressing production of a fine powder by polymerizing an olefin using a catalyst that includes the solid catalyst component.
