PURPOSE:To eliminate ply separation while increasing bending strength. CONSTITUTION:A multilayer ceramic board is manufactured in such a manner that a fact that a shrinkage factor is increased when glass powder and ceramic powder, particle size distribution of which is brought close, and the shrinkage factor is reduced when glass powder and ceramic powder having separate particle size distribution are employed is utilized, and the baking shrinkage factors of green sheets are approximated, and the green sheets are laminated and baked when the mixing ratio of glass powder and ceramic powder is changed and the green sheets of different kinds are prepared and the green sheets are laminated and the multilayer ceramic board is formed. |
