PROBLEM TO BE SOLVED: To provide a method for producing a polyolefin resin composition of excellent productivity restraining a small particle size of fine particle from being scattered when compounded, and reducing a dispersion of a physical property. SOLUTION: This method for producing the polyolefin resin composition includes (1) a process for obtaining a liquid-deposited polyolefin resin A by mixing 0.1-10 pts.wt. of liquid b having 0.1-100 cPs or less viscosity at 20°C, to 100 pts.wt. of polyolefin resin a having 3-20 mm of average particle size, using a mixer, (2) a process for obtaining a polyolefin resin mixture B by adding 0.01-50 pts.wt. of powder c having 0.001-0.5 mm average particle size, to 100 pts.wt. of the liquid-deposited polyolefin resin A, followed by mixing using a mixer, and (3) a process for obtaining the polyolefin resin composition, by melt-kneading the polyolefin resin mixture B, using a kneader.
