Abstract: A graphene grid that can reduce or prevent uneven distribution, uneven orientation, and the like of a structural analysis target substance, and can capture the structural analysis target substance with high efficiency and analyze the structural analysis target substance with high resolution, in structural analysis by cryo-electron microscopy. To achieve the above object, the graphene grid has a graphene surface onto which a functional group containing at least one of a silicon atom or a phosphorus atom is introduced.
