    Abstract: The present invention relates to a solid catalyst component for &agr;-olefin polymerization having a narrow particle size distribution of not less than 6.0 in terms of the value of N in a Rosin-Rammler function of particle size distribution and giving a catalytic activity of not less than 10,000 ((g-polymer produced/g-solid catalyst component)/hour) in polymerization. According to the present invention, there can be provided a solid catalyst component for &agr;-olefin polymerization capable of giving a poly-&agr;-olefin having the high bulk density and favorable particle properties with high catalytic activity.
