PROBLEM TO BE SOLVED: To provide a drying method for a solid catalyst component for olefin polymerization which lessens the amount of an adhering solvent while suppressing the falling of activity, and to provide a manufacturing process for the solid catalyst component for olefin polymerization less in the amount of the adhering solvent and having high activity. SOLUTION: As for the solid catalyst component for olefin polymerization which contains titanium atom, magnesium atom and a halogen atom and has an adhering solvent, the drying method of it comprises conducting through-flow drying, i.e., heating under inert gas flow in a condition where the endpoint temperature of the falling-drying-rate period becomes 88°C or lower, and then drying under reduced pressure for 12 hours or more. The manufacturing process for the solid catalyst component for olefin polymerization includes the step of performing the above drying method. COPYRIGHT: (C)2006,JPO&NCIPI
