Disclosed is a resin bead for cell culture that can be detached and recovered as it is without denaturing proliferated cells. A temperature-sensitive swelling resin bead for cell culture, comprising a cross-linked polymer (A) having an inflection point in a temperature-water absorption curve, and the temperature corresponding to the inflection point is 0. The crosslinked vinyl polymer (A1), the crosslinked alkylene oxide polymer (A2), and the crosslinked methylcellulose having a vinyl monomer containing a carbamoyl group and / or a polyoxyalkylene group as an essential constituent monomer. It is at least one selected from the group consisting of (A3) and a crosslinked saponified polyvinyl alcohol (A4). Furthermore, the temperature-sensitive swelling resin beads for cell culture, comprising a polypeptide (P) having at least one cell adhesion minimal amino acid sequence (X) in one molecule, and further comprising fine particles (b) .
