Provided is a heat conducting member using a heat conducting material that has been developed so as to retain the same heat conductivity as that of a conventional product without using silicone rubber. The heat conducting member comprises a base material formed from any of rubber, resin, paint or cement and, contained in the base material, a burned plant material selected from any of soybean hull, rapeseed lees, sesame lees, cottonseed lees, cotton hull, soybean chaff, or cacao husk, and is produced by controlling either the burned plant material content of the base material or the temperature at which the plant material is burned.
