Zusammenfassung:	To provide a composition containing a biodegradable resin which can give a molded article less prone to deterioration in tensile strength and elongation at breaking.SOLUTION: A resin composition includes a biodegradable resin and heavy calcium carbonate. The mass ratio of the biodegradable resin to the heavy calcium carbonate is 10:90 to 70:30. The biodegradable resin includes at least polybutylene adipate terephthalate or polybutylene succinate adipate.SELECTED DRAWING: None 【課題】本発明の課題は、引張強さ及び切断時伸びの低下が抑制された成形品を得ることができる、生分解性樹脂含有組成物を提供することである。【解決手段】本発明は、生分解性樹脂と、重質炭酸カルシウムとを含み、前記生分解性樹脂と、前記重質炭酸カルシウムとの質量比が１０：９０～７０：３０であり、前記生分解性樹脂が、ポリブチレンアジペートテレフタレート又はポリブチレンサクシネートアジペートを少なくとも含む、樹脂組成物を提供する。【選択図】なし
