Abstract

Provided is a solid catalyst component for olefin polymerization capable of suitably producing polymer particles with a suppressed content ratio of fine powder and reduced surface stickiness at high activity when subjected to polymerization of an olefin. The solid catalyst component for olefin polymerization contains magnesium, titanium, halogen and an internal electron-donating compound, in which a cross-sectional pore area ratio is 10 to 50%, and a ratio MX/MXof a cross-sectional pore area ratio (MX) in a region of less than 50% in a radial direction to a cross-sectional pore area ratio (MX) in a region of 50% or more in the radial direction from a particle center is 0.50 to 2.00.
