It is possible to form a sheet by blending the above ingredients, adding various additives as necessary, and using a doctor blade method, roll forming method, etc. As the thermosetting resin, various kinds of ordinary epoxy resins, urethane resins, phenolic resins, etc. can be used, but it is particularly preferable to use an epoxy resin together with a heat-activated curing agent.As the epoxy resin, ordinary glycidyl Various epoxy resins such as ether type, glycidyl ester type, glycidyl amine type, and linear aliphatic epoxide type can be used, and one type can be used alone or two or more types can be used in combination depending on the physical properties required for the green sheet. . Further, as the heat-activated curing agent, a normal curing agent that exhibits curing action by heating may be used, and generally 800
It is sufficient if it is active in the temperature range ~200°C, for example, dicyandiamide, 4,4'-diaminodiphenylsulfone, imidazole derivatives such as 2-n-heptadecyl imidazole, isophthalic acid dihydrazide, N,N
-Dialkylurea derivatives and the like are used. The amount used is
The amount may be generally 1 to 15 parts by weight per 100 parts by weight of the epoxy resin.

They can be used alone or in combination of two or more. The amount of resin added is preferably 1 to 3 parts by weight per 100 parts by weight of the ceramic powder, but considering shrinkage during firing, it is recommended to add the same amount as the first ceramic composition layer. preferable.

。The green sheet of the present invention is made by laminating and integrating the first ceramic composition layer and the second ceramic composition layer as described above, and this lamination and integration is performed to the extent that curing does not proceed completely. They may be fused by heating, or they may be fused using a solvent. The thickness of this sheet varies depending on the ceramic powder used and the application, but generally the thickness of the first ceramic composition layer is 0.05~
