Zusammenfassung:	To provide a moisture absorbing antibacterial resin composition capable of molding a molded body having antibacterial effect at a low addition amount since deterioration of a substrate resin is low and dispersibility of antibacterial agent is good, and the molded body.SOLUTION: The above described problem is solved by a moisture absorbing antibacterial resin composition containing shell burning calcium (A) having average particle diameter of 3 to 20 μm and time till moisture absorbing amount reaches equilibration under temperature of 23°C, humidity 50%RH environment of 65 to 130 hrs, and a thermoplastic resin (B), and a molded body by molding the moisture absorbing antibacterial resin composition.SELECTED DRAWING: None 【課題】本発明は、基材樹脂の劣化が少なく、抗菌剤の分散性が良好なため、低添加量で抗菌効果を有する成形体を成形できる吸湿性抗菌樹脂組成物および成形体の提供を目的とする。【解決手段】前記課題は、平均粒子径３〜２０μｍ、かつ温度２３℃、湿度５０％ＲＨ環境下で吸湿量が平衡に達するまでの時間が６５〜１３０時間の貝殻焼成カルシウム（Ａ）と、熱可塑性樹脂（Ｂ）とを含む吸湿性抗菌樹脂組成物、および前記吸湿性抗菌樹脂組成物を成形してなる成形体により解決される。【選択図】なし
