Abstract: Provided are: a nucleating agent for a polyolefin resin having an excellent β crystal-forming effect; a nucleating agent composition for a polyolefin resin containing the nucleating agent; a polyolefin resin masterbatch; a polyolefin resin composition; a molded article of the composition; a film of the composition; a method of producing a porous film; and a package. The nucleating agent contains a compound represented by Formula (1) below wherein M represents a monovalent to trivalent metal atom having a specific gravity of 4.0 or less, or the like; a represents 1 or 2; b represents 1 or 3; x represents an integer of 1 to 3; ax=2b is satisfied; and Z represents a group represented by Formula (2) or (3) below wherein * represents a position at which each group is linked with Z of Formula (1); Y represents a direct bond or an alkylene group having 1 to 4 carbon atoms; and R1 to R10 each independently represent a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1 to 10 carbon atoms, or the like.
