PROBLEM TO BE SOLVED: To provide a catalyst for olefin polymerization having high activity, having good bulk density and particle properties of catalyst powder, suppressing adhesion to polymerization reactor wall, etc., in a catalyst feed step and a polymerization step and capable of continuing stable polymerization operation. SOLUTION: The catalyst composition for olefin polymerization is obtained by mixing a solid catalyst component [A] for olefin polymerization containing a transition metal compound (component [a]) of group III to X of the periodic table and a cocatalyst support (component [b]) with inorganic oxide fine particles (component [B]) having≥35% hydrophobization degree in a weight ratio of 0.0001-0.1.
