(57) [Summary] [Structure] [A] A metallocene-based transition metal compound, [B] a clay having an average particle size of 10 μm or more, a clay mineral or an ion-exchange layered compound, and [C] an organoaluminum compound. An olefin polymerization catalyst comprising a product. [Effect] According to the present invention, an olefin polymer having a high bulk density and a small amount of fine powder and good particle properties can be obtained with sufficiently high polymerization activity. |
