It is a main object of the present invention to provide a bonded body capable of facilitating bonding of a metal layer and a carbon material layer while increasing the thickness of the metal layer, and also capable of suppressing breakage, and a manufacturing method thereof. A sintered tungsten carbide layer 5 and a mixed layer 6 of SiC and WC 6 are formed between the CFC layer 3 and the tungsten layer 4 as a joined body of a structure in which the CFC layer 3 and the tungsten layer 4 are bonded. ), And SiC and WC (7) sintered and infiltrated into the CFC layer are formed, and these layers 3, 4, 5, 6, and 7 are bonded by the sintering method. |
