Abstract: Provided are a nucleating agent for polyolefin resin having an excellent β crystal-forming action, a nucleating agent composition for polyolefin resin containing the same, a master batch for polyolefin resin, a polyolefin resin composition, a molded article thereof, a film thereof, a method for producing a porous film, and a package. The nucleating agent for polyolefin resin includes a compound represented by general formula (1) (In general formula (1), M represents a monovalent to trivalent metal atom or the like having a specific gravity of 4.0 or less, a represents 1 or 2, b represents 1 or 3, x represents an integer of 1-3, and these satisfy ax = 2 b. Z represents a group represented by general formula (2) or (3). ( In general formula (2) and (3), * represents a linking position with Z in general formula (1), Y represents a direct bond or a C1-4 alkylene group, R
