▎ 摘　　要

NOVELTY - The body (1) has a substrate portion (2) composed of silicon carbide. A graphene film (3) is fixed on a main surface (2a) of the substrate portion. The graphene film comprises 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 being not less than 10% in an area ratio in an exposed surface (3A) of the graphene film. The exposed surface is a main surface of the graphene film opposite to the substrate portion. USE - Laminated body for use in an electronic device (claimed) i.e. FET. ADVANTAGE - The body has high mobility, and can be stably secured while manufacturing an electronic device with the graphene film serving as a conductive portion. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a structure of a FET including a graphene film.
