An electricity storage material according to the present invention contains a copolymer compound of first units and second units, each first unit having a side chain which is an oxidation-reduction site having a it conjugate electron cloud and being of a structure represented by general formula (1) below, and each second unit having no oxidation-reduction reaction site as a side chain. In general formula (1), X 1 to X 4 are, independently, a sulfur atom, an oxygen atom, a selenium atom, or a tellurium atom; R 1 and R 2 are, independently, an acyclic or cyclic aliphatic group including at least one kind selected from the group consisting of a carbon atom, an oxygen atom, a nitrogen atom, a sulfur atom, a silicon atom, a phosphorus atom, and a boron atom, each including at least one or more double bonds; and one of R 1 and R 2 includes a bonding hand for binding to another portion which is a main chain or a side chain of the copolymer compound. |
