Abstract
Provided is a resin film having excellent cell extensibility in cell culture. The resin film formed of a scaffold material for cell culture containing a synthetic resin, the resin film having a compressive modulus of 5.5 GPa or more at a frequency of 1 Hz as measured using a nanoindenter device in ion-exchanged water in accordance with ISO14577-1 after being immersed in the ion-exchanged water at 37° C. for 24 hours.
