摘要：
To provide a method of efficiently affording olefin polymers having a high molecular weight and a high melting point even under industrially advantageous high-temperature conditions. A production method of an olefin polymer to solve the above problem includes polymerizing monomer(s) including at least one α-olefin having 3 or more carbon atoms at 50° C. to 200° C. in the presence of an olefin polymerization catalyst including; (A) a crosslinked metallocene compound represented by General Formula [I] below; and (B) at least one compound selected from (b-1) an organoaluminum oxy-compound, (b-2) a compound that forms an ion pair by reacting with the crosslinked metallocene compound (A), and (b-3) an organoalunimum compound.
