A process is provided by which a polyrotaxane including cyclic molecules having a relatively long graft chain is easily obtained. Also provided is a polyrotaxane which includes cyclic molecules having a radical polymerization initiation site and is for use as a raw material in the process. The polyrotaxane comprises: a pseudo-polyrotaxane comprising cyclic molecules clathrated with a linear molecule, the cavities of the cyclic molecules having been pierced by the linear molecule; and blocking groups disposed respectively at both ends of the pseudo-polyrotaxane so as not to release the cyclic molecules. The cyclic molecules in the polyrotaxane have a radical polymerization initiation site.
