ABSTRACT:
A method for manufacturing a composite sintered structure, comprising the steps of preparing a green ceramic sheet, printing a green ceramic insulator paste and a conductor paste on the green ceramic sheet, and sintering the resulting lamination to form a monolithic structure, the green ceramic sheet and the insulator and conductor pastes being made of the same starting ceramic base materials, so that the difference in the coefficient of shrinkage between the green ceramic sheet and the printed insulator and conductor layers is eliminated.
