Abstract
A substrate includes: a support substrate having a first main surface and a surface layer region which includes at least the first main surface and is formed of any one material selected from the group consisting of boron nitride, molybdenum disulfide, tungsten disulfide, niobium disulfide, and aluminum nitride; and a graphene film disposed on the first main surface and having an atomic arrangement oriented in relation to an atomic arrangement of the material forming the surface layer region. Accordingly, the substrate is provided that enables a high mobility to be stably ensured in an electronic device manufactured to include the graphene film forming an electrically conductive portion.
