A high value-added carbide obtained by using jatropha fruits, a material derived from jatropha fruits and/or a material derived from sugar cane. A method for producing the carbide, said method comprising mixing at least one kind of material selected from among jatropha fruits (A), a material (B) derived from jatropha fruits and a material derived from sugar cane with fermenting microorganisms (C), and carbonizing the mixture by adding photo energy thereto. In this method, it is preferred that said mixture is carbonized while being maintained at a low temperature of 80-90oC inclusive. The fermenting microorganisms (C) comprise at least one kind of bacterium selected from among a photosynthetic bacterium, a photothermal bacterium, a lactic acid bacterium, a nitrogen fixing bacterium, a yeast and an actinomycete.
