1. A base material for tissue reconstruction that is mainly composed of either one of a polyrotaxane and a polyrotaxane hydrogel, where the polyrotaxane has biocompatible groups, each of which has a bulky substituent and is introduced via a hydrolytic bond to either terminal of a linear molecule with multiple cyclic molecules threaded thereon, and the polyrotaxane hydrogel has a network structure formed by crosslinking between the cyclic molecules, between the biocompatible groups, or between the cyclic molecule and the biocompatible group in adjoining molecules of the polyrotaxane.
