PROBLEM TO BE SOLVED: To provide a method for manufacturing a glass ceramic substrate having a very high dimensional accuracy and a good surface condition by surely constraining a sintering contraction of a glass ceramic green sheet. SOLUTION: This method comprises (i) forming laminated bodies 1 by laminating a number of glass ceramic green sheets on the surfaces of which conductive patterns are formed, (ii) laminating alternatively a laminated body 1 and a constrained green sheet 2 which contain hardly sinterable inorganic materials by setting the green sheets 2 at the top layer and the bottom layer and intercalating an adhesive agent layer containing glass and a solvent, (iii) eliminating organic constituents from the laminated bodies and then sintering and forming a glass ceramic substrate holding the constrained sheets and (iv) eliminating the constrained sheets from the substrate, (v) while the glass content of the adhesive agent layer is equal to the amount used to combine the green sheets and the glass ceramic green sheets at the time of sintering and eliminated from the substrate together with the constrained sheets after sintering. |
