ABSTRACT:
A reinforced plate-like laminated sintered body is produced by the steps of providing a green laminate with an alumina-based layer including zirconia provided at least partly over one surface of the base material and simultaneously sintering the laminated surface layer and base material layer. The thickness ratio of the surface layer with respect to the base material layer is in the range of 1/100 to 20/100 and the laminate has a ratio of shrinkage moduli, calculated as the ratio of the shrinkage modulus of the base material layer when sintered alone to the shrinkage modulus of the surface layer when sintered alone, within the range of 1.01 to 1.08.
