摘要：
A method of producing a prepolymerized catalyst for olefin polymerization comprising a fine powder removal step of removing fine particles from olefin-prepolymerized catalyst particles for olefin polymerization. The prepolymerized catalyst having a low fine particle content is applicable suitably to the field of continuous polymerization of olefins.
