PROBLEM TO BE SOLVED: To obtain a solid fuel capable of continuing a combustion by such a weak cooking fire as not to scorch a food even after the food in a small pan is boiled up and reserving the heat of the food in the small pan. SOLUTION: This solid fuel is characterized in that the lower part of a main combustion part layer 2a formed by solidifying a fixed amount of a combustible material 2 such as wax, paraffin, etc., is provided with a combustion part layer 2b for heat insulation to be burned at a weaker fire than that of the main combustion part layer 2.
