PROBLEM TO BE SOLVED: To provide a method for producing a polyolefin composition having many kinds of constituents using a more simplified apparatus in a method of producing a polyolefin composition by melt kneading the polyolefin with additives. SOLUTION: The method for producing a polyolefin composition by melt kneading the polyolefin with several additives comprises under-mentioned first process to third process;the first process: a process to blend preliminarily at least two sorts of polymer pellets selected from several polyolefins and/or elastomers, the second process: a process to blend a mixture obtained by the first process with powdered polyolefins and other additives, the third process: a subsequent process to produce the polyolefin composition by introducing the resulted mixture into a melt kneading machine.
