1. A surface-modified carbon material comprising:
multiple chemical addends provided on at least a part of a surface of a carbon material selected from the group consisting of graphene, graphite, a glassy carbon film, and film-like pyrolytic carbon, and
a one-dimensional periodicity corresponding to addition positions of the multiple chemical addends,
wherein the one-dimensional periodicity corresponding to the addition positions of the multiple chemical addends can be observed in a Fourier-transformed image of a scanning probe microscopic image of the surface, and
wherein a pitch corresponding to the one-dimensional periodicity is 2 to 10 nm.
