1. A conductive composite material comprising:
particles of a layered material including one or plural layers, wherein the one or plural layers include a layer body represented by:
MmXn
 where M is at least one metal of Group 3, 4, 5, 6, or 7,
X is a carbon atom, a nitrogen atom, or a combination thereof,
n is not less than 1 and not more than 4,
m is more than n but not more than 5, and
a modifier or terminal T exists on a surface of the layer body, where T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom, or a hydrogen atom; and
a polymer material that includes a hydrogen acceptor that is at least one selected from the group consisting of a fluorine atom, a chlorine atom, an oxygen atom, or a nitrogen atom; and a hydrogen donor that is a hydroxyl group and/or a secondary amino group,
wherein a ratio of the particles of the layered material to the conductive composite material is more than 19% by volume but not more than 95% by volume, and
wherein the polymer material is one or more of polyethylenimine, polypyrrole, polyaniline, polyimide containing a secondary amino group, polyamide imide, polyacrylamide, nylon, deoxyribonucleic acid, acetanilide, and acetaminophen.
