Disclosed is a crystalline nucleating agent composition for a polyolefin resin providing a polyolefin resin composition superior in transparency and having an excellent fluidity as powder. The crystalline nucleating agent for polyolefin resin composition, comprises, per 100 parts by mass of (C) 1,3:2,4-bis(3',4'-dimethylbenzylidene)sorbitol, 3 to 20 parts by mass of (D) a phosphoric acid ester metal salt compound represented by the following general formula (3), (wherein R 1 to R 4 each independently represents a hydrogen atom or an alkyl group having 1 to 9 carbon atoms; R 5 represents a hydrogen atom or a methyl group; n represents 1 or 2; when n is 1, M represents an alkali metal; and when n is 2, M represents Al(OH)), and 0.5 to 10 parts by mass of (E) a compound which is a monovalent metal salt of fatty acid having 12 to 22 carbon atoms, optionally substituted by hydroxy group, and wherein (D)/(E), the mass ratio between (D) the phosphoric acid ester metal salt compound and the compound (E), is within a range from 90/10 to 50/50.
