This invention makes it easier to control a volume specific resistivity, and provides the electrically conductive composition which can be manufactured from the carbon-based material of a plant fired material single body. According to the present invention, one of soybean hulls, rapeseed meal, sesame seed meal, cottonseed meal, cotton hull, rice husk, rice bran, soybean husk, rice flour, grain husk Plant firing products, such as these, are manufactured. The milled product after carbonization of a plant is sieved so that a median diameter may be about 80 micrometers or less. The plant fired material is fired at a temperature of 700 [° C] or higher. |
