Provided is an electrically conductive composition capable of making specific volume resistivity control easier, which can be produced by using a carbonaceous material comprising a burned plant material alone. A burned plant material is produced from soybean hulls, rapeseed meal, sesame meal, cotton seed meal, cotton hulls, rice hulls, rice bran, soybean chaffs, rice straws, cereal hulls or the like by adjusting any of the carbon content, burning temperature and median diameter. The burned and carbonized plant material is ground and sieved to give a median diameter of approx. 80μm or below. The burned plant material is obtained by burning at a temperature of 700° C. or higher.
