PROBLEM TO BE SOLVED: To provide a molding resin composition containing a nucleating agent suitable for accelerating the crystallization of a crystallizable polyester, especially a biodegradable polyester and provide a molded article containing the molding resin composition having improved crystallizability. SOLUTION: The resin composition contains a crystallizable polyester and a cyclic compound expressed by general formula (I) (A<SB>1</SB>, A<SB>2</SB>, A<SB>4</SB>and A<SB>5</SB>are each independently CO or NH; and A<SB>3</SB>and A<SB>6</SB>are each independently H, a halogen, a (substituted) aliphatic group or a (substituted) aromatic group) and having CO and NH in the molecule or a mixture of (a) a cyclic compound containing CO in the molecule and free from NH in the molecule and (b) a cyclic compound containing NH in the molecule and free from CO in the molecule.
