PROBLEM TO BE SOLVED: To develop an olefin polymerization catalyst exhibiting sufficient performance in all catalytic performances such as stereoregularity, catalyst activity and a property of a polymer particle, and a manufacturing method for such a catalyst component. SOLUTION: In the manufacturing method for the solid catalyst component (A1) for α-olefin polymerization, the solid component obtained by treating a magnesium compound by a copper compound is treated by a titanium compound, a halogen compound and an electron-donating compound. Alternatively, in the manufacturing method for the catalyst component for α-olefin polymerization, the solid catalyst component (A1) is subjected to contact treatment by the components (A2), (A3) and (A4). Component (A2): a silicon compound having an alkenyl group, component (A3): an organic silicon compound, and component (A4): an organic aluminum compound. COPYRIGHT: (C)2010,JPO&INPIT
