The modified graphene includes a structure represented by the following formula (I), wherein the modified graphene has a ratio (g/d) of an intensity “g” of a G band to an intensity “d” of a D band of 1.0 or more in a Raman spectroscopy spectrum thereof:
Gr1-Ar1-X1-(Y1)
n1
(I)
in the formula (I), Gr1 represents a single-layer graphene or a multilayer graphene, Ar1 represents an arylene group having 6 to 18 carbon atoms, X1 represents a single bond, a linear, branched, or cyclic alkylene group having 1 to 20 carbon atoms, or a group obtained by substituting at least one carbon atom in a linear, branched, or cyclic alkylene group having 1 to 20 carbon atoms with at least one structure selected from the group consisting of —O—, —NH—,
—CO—, —COO—, —CONH—, and an arylene group.
