PROBLEM TO BE SOLVED: To provide: a carbonaceous refractory that suppresses erosion of a melting furnace lining material to elongate the life of a melting furnace and suppresses heat loss (radiation heat loss) to suppress energy loss, and that is easily and inexpensively producible; and a method of producing the carbonaceous refractory.SOLUTION: A carbonaceous refractory 1 includes a high heat conductive part 2 disposed on one side, and a low heat conductive part 3 that is disposed on the other side and has a lower thermal conductivity than the high heat conductive part 2. The high heat conductive part 2 is made of a high heat conductive material composed mainly of an artificial graphite as a carbon source. The low heat conductive part 3 is made of a low heat conductive material composed mainly of anthracite as a carbon source. The carbonaceous refractory 1 is formed by integrally molding and firing the high heat conductive material and the low heat conductive material. 【課題】溶融炉内張材の溶損を抑制し溶融炉の高寿命化を図ることができると共に、熱損失（放散熱量）を抑制してエネルギー損失を抑えることができ、さらに、製造が容易で低廉に作製することができる炭素質耐火物およびその製造方法を提供する。【解決手段】本発明の炭素質耐火物１は、一方側に配された高熱伝導部２と、他方側に配され前記高熱伝導部２に比して低い熱伝導率を示す低熱伝導部３とを有した炭素質耐火物であって、高熱伝導部２はカーボン源として人造黒鉛を主材とする高熱伝導材にて形成され、低熱伝導部３はカーボン源として無煙炭を主材とする低熱伝導材にて形成され、炭素質耐火物１は、高熱伝導材と低熱伝導材とが一体成形され焼成されて形成されている。【選択図】図１
