A method for producing ethylene-based polymer particles by homopolymerizing ethylene or copolymerizing ethylene and a C 3-20 linear or branched α-olefin in the presence of an olefin polymerization catalyst containing: (A) micro-particles provided with an average particle diameter of 1—300 nm and obtained through at least two steps in which step 1 is a step in which a metal halide and an alcohol are brought into contact with each other in a hydrocarbon solvent, and in which step 2 is a step in which the component obtained in step 1 is brought into contact with an organoaluminum compound and/or an organoaluminumoxy compound; and (B) a transition metal compound represented by General Formula (I) or (II), the method satisfying condition (E), that is, that the limiting viscosity (η), as measured at 135°C in a decalin solvent, be 5—50 dL/g. |
