Cell culture container capable of long-term culture and method for manufacturing same

A cell culture container for long term non-adherent cell culture which comprises having a coating containing a copolymer which is a copolymer having a recurring unit which contains a group represented by the following formula (a), a recurring unit which contains a group represented by the following formula (b), and a recurring unit which contains a group represented by the following formula (c):

• wherein,
• Ua1, Ua2, Ub1, Ub2 and Ub3 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms;
• Rc represents a linear or branched alkyl group having 1 to 10 carbon atoms, an alicyclic hydrocarbon group having 3 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, an aralkyl group having 7 to 15 carbon atoms or an aryloxyalkyl group having 7 to 15 carbon atoms, where the aryl portion may be substituted by a linear or branched alkyl group having 1 to 5 carbon atoms which may be substituted by a halogen atom(s);
• and
• An− represents an anion selected from the group consisting of a halide ion, an inorganic acid ion, a hydroxide ion and an isothiocyanate ion, and
• a molar ratio of the recurring unit which contains a group represented by the formula (c) being 1 to 50 mol % based on the whole copolymer, provided with at least a part of a surface thereof.
