Container

The purpose of the present invention is to provide a container in which non-specific adsorption of a protein to the inner wall surface of a storage member is reduced. The container according to the present invention has a storage member formed by molding a molding material containing a resin, and the inner wall surface of the storage member has a Zeta potential of less than-40.0 mV at a pH of 7.0 and a dispersion component of surface free energy of less than 24.5 mJ/m2. 本发明的目的在于提供一种减少了蛋白质对收纳构件的内壁面的非特异性吸附的容器。本发明的容器具有将包含树脂的成型材料成型而成的收纳构件，上述收纳构件的内壁面在pH为7.0时的Zeta电位小于－40.0mV，表面自由能的色散分量小于24.5mJ/m2。
