Disclosed is a polyolefin resin composition which has an excellent transparency even when the polyolefin resin has a high melt flow rate (MFR). The polyolefin resin composition comprises a polyolefin resin having a melt flow rate (MFR) at 230 °C of 20 dg/min or more, (A) a dibenzylidene sorbitol compound represented by the following general formula (1),
(wherein n represents an integer of 0 to 2; and R1, R2, R3, R4, and R5 each independently represent a hydrogen atom or the like) and (B) an alkali metal salt compound of organic phosphoric acid ester represented by the following general formula (2),
(wherein R6 to R9 each independently represent a hydrogen atom or the like), and wherein the sum of the amount of the component (A) and the component (B) is 0.01 to 1.0 part by mass per 100 parts by mass of the polyolefin resin, and (A)/(B), the ratio (mass ratio) between the component (A) and the component (B), is within a range from 99/1 to 80/20.
