A material which comprises a polyrotaxane and a polymer and is crosslinked by irradiation with light. In the material, which comprises a first polyrotaxane and a polymer, the first polyrotaxane comprises first cyclic molecules, a first linear molecule with which the first cyclic molecules are clathrated in a spitted state, and first blocking groups disposed respectively at both ends of the first linear molecule so as to prevent the first cyclic molecules from being released from the first linear molecule. The first polyrotaxane combines with at least part of the polymer through the first cyclic molecules by photocrosslinking reaction. |
