1. A macromolecular material comprising a polymer having a host group and a guest group, wherein
the host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative,
the cyclodextrin derivative has a structure formed such that a hydrogen atom of at least one hydroxy group contained in a cyclodextrin is replaced with at least one group selected from the group consisting of a hydrocarbon group, an acyl group, and -CONHR wherein R represents a methyl group or an ethyl group,
the polymer is a polymer of a monomer mixture containing a host group-containing polymerizable monomer, a guest group-containing polymerizable monomer, and a third polymerizable monomer,
the third polymerizable monomer contains a (meth) acrylic ester compound,
the host group-containing polymerizable monomer and the guest group-containing polymerizable monomer have a property of being dissolved in the third polymerizable monomer,
the mixture of the host group-containing polymerizable monomer and the guest group-containing polymerizable monomer in a total amount of 1 part by weight or more is dissolved per 100 parts by weight of the third polymerizable monomer at a temperature of 20° C., and
the third polymerizable monomer comprises at least one selected from the group consisting of 2-methoxyethyl acrylate, tetrahydrofurfuryl acrylate, 2-phenylethyl acrylate and 4-hydroxybutyl acrylate.
