Provided is a scaffold material for cell culture with which the culture stability of cells can be maintained over an extended period of time. A scaffold material for cell culture according to the present invention contains a peptide-conjugated (meth)acrylic copolymer having a (meth)acrylic copolymer moiety and a peptide moiety bonded to the (meth)acrylic copolymer moiety, the following relaxation time (CS.sub.2) being 5 milliseconds or less. Relaxation time (CS.sub.2): a relaxation time of a CS component, which is a component having the lowest molecular mobility among three components, when the scaffold material for cell culture after being brought into contact with heavy water at 25 C. for 18 hours is measured by a CPMG method using pulsed NMR, and the obtained free induction decay curve of spin-spin relaxation of .sup.1H is separated into three components.

Provided is a coating solution for forming a cell scaffold with which a cell scaffold having a large thickness can be easily formed and the proliferation of cells can be enhanced. A coating solution for forming a cell scaffold according to the present invention contains a peptide-conjugated resin having a synthetic resin moiety and a peptide moiety and an alcohol solvent, a content of the peptide-conjugated resin being 0.1 wt % or more.
