Abstract
A laminated body includes: a substrate portion composed of silicon carbide; and a graphene film disposed on a first main surface of the substrate portion, the graphene film having an atomic arrangement oriented with respect to an atomic arrangement of the silicon carbide of the substrate portion. A region in which a value of G'/G in Raman spectrometry is not less than 1.2 is not less than 10% in an area ratio in an exposed surface of the graphene film, the exposed surface being a main surface of the graphene film opposite to the substrate portion.
