Abstract
[Means for solving]A graphene oxide sheet which changes to a substance having a graphene structure when reduced, and which is obtainable by dispersing a graphene-containing carbon substance using a dispersant to reduce the size of the aggregate units of the graphene-containing carbon substance, and then oxidizing the graphene-containing carbon substance.
