The present invention provides a polyrotaxane for obtaining a material combining a higher degree of elongation with a higher breaking strength and/or a polyrotaxane having properties not possessed by conventional polyrotaxanes, such as compatibility with compounds to be used in a material, solubility in solvents, and functionality. The polyrotaxanes of the present invention each comprise: a pseudo-polyrotaxane comprising cyclic molecules and a linear molecule which passes through the cavities of the cyclic molecules to form a clathrate; and blocking groups disposed at both ends of the pseudo-polyrotaxane so that the cyclic molecules are not released. The cyclic molecules each include a hydroxyl-inactivation group and a hydroxyl group bonded by a spacer group. The polyrotaxanes have a hydroxyl value of 10-65 mg-KOH/g.
