The present invention provides a solid catalyst component for polymerization of an olefin, which appropriately suppresses a decrease in polymerization activity per unit time when having been supplied to the polymerization of the olefin, even without using a phthalic acid ester, and can easily prepare a polymer of an olefin, in which drying efficiency is improved, and a content ratio of a remaining volatile organic compound is greatly reduced in a short period of time. The solid catalyst component for polymerization of an olefin includes magnesium, titanium, halogen and a 1,3-diether compound, wherein a ratio of the 1,3-diether compound contained in the solid catalyst component for polymerization of an olefin is 2.50 to 15.00% by mass, and a specific surface area of the solid catalyst component for polymerization of an olefin is 250 m.sup.2/g or larger.
