It is a layer formed of metals such as, or a layer mainly composed of these metals. A plurality of metal and ceramic mixture layers 4 (three layers in FIG. 1) are formed between the uppermost layer 2 and the lowermost layer 3. This mixture layer 4 is formed of a mixture of ceramics forming the top layer 2 and metal forming the bottom layer 3, and each layer is arranged from the top layer 2 side to the bottom layer 3 side. The composition is such that the metal content increases sequentially. A molded body 1 formed by laminating such layers is sintered in a firing furnace 10.

A cooling line passageway (not shown) is provided inside, and by passing cooling water or cooling gas through this passage, the temperature on the layer 3 side can be set lower than the temperature on the layer 2 side. can. Then, the inside of the firing furnace 10 is set to the sintering temperature T1 of the uppermost layer 2 under a vacuum of, for example, about 1O-1 Torr, and the cooling conditions of the base member 12 are set such that the temperature of the layer 3 becomes an appropriate temperature T2. is set appropriately, and furthermore, the pressure member 11

きる。In this case, since the sintering temperature of metals is usually lower than the sintering temperature of ceramics, the compact can be fired under appropriate sintering conditions by adjusting the firing temperature in this manner. In addition, since the metal content of each layer increases sequentially, distortion between each layer during the sintering process is less likely to occur, and even when the laminate is heated during use after sintering, the thermal stress generated in each layer is small. . Furthermore, by applying pressure during the sintering process, deformation of the product during firing can be prevented.
