Abstract: Provided are: an olefin-based resin composition that can yield a molded article having excellent transparency in which coloration is inhibited; a method for producing the olefin-based resin composition; and a molded article of the olefin-based resin composition. The olefin-based resin composition contains, with respect to 100 parts by mass of an olefin polymer: 0.001 to 10 parts by mass of one or more compounds (A) represented by Formula (1) wherein R1 to R4 each independently represent a hydrogen atom or an alkyl group having 1 to 9 carbon atoms; R5 represents a hydrogen atom or methyl; m represents 1 or 2; and M1 represents, for example, a hydrogen atom; and 0.001 to 10 parts by mass of a fatty acid metal salt (B) represented by Formula (2) wherein R6 represents a group having 10 to 30 carbon atoms and introduced from an aliphatic organic acid; n represents 1 or 2; and M2 represents an alkali metal atom or a multivalent metal inorganic group. In the olefin-based resin composition, an aluminum content in the olefin polymer is 0.01 mol or less per 1 kg of the olefin polymer.
