PROBLEM TO BE SOLVED: To provide a nucleating agent composition which improves the solubility and dispersibility of an amide compound in a polyolefin resin composition and is easy to industrially handle. SOLUTION: The polyolefin resin composition is formed by incorporating a nucleating agent for polyolefins comprising at least one kind of an amide compound selected from the group consisting of R<SP>1</SP>-(CONHR<SP>2</SP>)<SB>m</SB>of formula (1) (wherein R<SP>1</SP>is an aliphatic polycarboxylic acid residue, an alicyclic polycarboxylic acid residue or an aromatic polycarboxylic acid residue and 2-6 pieces of R<SP>2</SP>are each an aliphatic monoamine residue, an alicyclic monoamine residue or an aromatic monoamine residue) and R<SP>3</SP>-(NHCOR<SP>4</SP>)<SB>n</SB>of formula (2) (wherein R<SP>3</SP>is an aliphatic polyamine residue, an alicyclic polyamine residue or an aromatic polyamine residue and 2-6 pieces of R<SP>4</SP>are each an aliphatic monocarboxylic acid residue, an alicyclic monocarboxylic acid residue or an aromatic monocarboxylic acid residue) and an antioxidant at a weight ratio of 1:1 to 1:10 into a polyolefin resin.
