It is intended to provide an apparatus for separating and storing blood components which facilitates the preparation of serum. An apparatus (1) for separating and storing blood components which comprises a blood pooling part (2) for pooling a fluid at least containing liquid components containing a blood-origin coagulation factors and platelets, a component storing part (3) for storing at least a part of the components of the fluid pooled in the blood pooling part (2), and a connector part (4) aseptically connecting the blood pooling part (2) to the component storing part (3), wherein the blood pooling part (2) comprises a blood pooling container (21) in the form of a flexible tube, a fluid inlet channel (27) for introducing the fluid into the blood pooling container (21) and a component outlet channel (28) for leading out at least a part of the components of the fluid； the component storing part (3) has a component inlet channel (37) for introducing at least a part of the components of the fluid having been led out form the blood pooling container (21)； and the connector part (4) connects the component outlet channel (28) to the component inlet channel (37).本發明提供一種可較為簡易地製備血清之血液成分分離收容裝置。該血液成分分離收容裝置1至少具備：血液儲存部2，其儲存包含含有源自血液的凝固因子之液態成分與血小板之流體；成分收容部3，其收容已儲存於血液儲存部2中之流體中的至少一部分成分；以及連結部4，其無菌地連結血液儲存部2與成分收容部3；其中上述血液儲存部2具有：具可撓性之筒狀血液儲存容器21、將流體導入血液儲存容器21中之流體導入路27、及將流體中的至少一部分成分由血液儲存容器21導出之成分導出路28；上述成分收容部3，具有成分導入路37，其導入由血液儲存容器21中導出之流體中的至少一部分成分；上述連結部4，連結成分導出路28與成分導入路37。
