Ethylene polymer particles having an intrinsic viscosity [&eegr;] of 5 dl/g to 30 dl/g, a degree of crystallinity of as high as 80% or more, and a specific shape on the surface of the particles. The ethylene polymer particles can be obtained by carrying out polymerization of olefins including ethylene using an olefin polymerization catalyst containing a solid titanium catalyst component including magnesium, halogen and titanium under specific conditions. The ethylene polymer particles obtained by a solid phase method, such as solid phase drawing molding, are capable of providing a molded article with high strength.
