NOVELTY - An amorphous carbon raw material produced from a plant raw material, and has unevenness containing microsilicon component and potassium component of 1 mu m or less. USE - Carbon raw material used for forming graphene (claimed). Uses include but are not limited to battery material, semiconductor applications, thermal radiation material, transparent conductive film, flexible thin film, filter, light and high-strength composite material, toner, and ink material. ADVANTAGE - The carbon raw material enables economical and efficient manufacture of large amount of graphene with high purity in a short period of time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) graphene, which comprises the carbon raw material as a precursor, in which the silicon component and the potassium component of the carbon raw material are removed and generated; (2) graphene manufacturing apparatus, which comprises a pressure regulation portion for adjusting the pressure in a chamber, a gas unit which switches and supplies multiple gas into the chamber, a heating portion provided with multiple types of heating, storage containers for expropriating materials to be heated, a movement heating apparatus for moving to the target storage container and switching the gas to be supplied for each heating type; and (3) manufacture of carbon raw materials, which involves heating the carbon source at a heating coefficient (K) value of 130- 280. The heating coefficient (K) is defined as the product of the heating area (H) and the calorific value area (ht). The heating area (H) is defined as the value obtained by dividing the heating surface area (S), which indicates the area when heated by the storage portion, by the heating volume (V), which indicates the volume when the carbon source is heated. The calorific value area (ht) is a value obtained by expressing the relationship between the heating time (h) of the carbonization source and the temperature of heating the carbonization source in terms of area.
