PROBLEM TO BE SOLVED: To provide a method for obtaining a glass ceramic board high in size precision by surely restraining the sintering contraction of a glass ceramic green sheet. SOLUTION: (i) A plurality of the glass ceramic green sheets forming a conductor pattern are laminated on the surface to manufacture a laminate 1, (ii) the restrained green sheet 2 containing a hardly sinterable inorganic material and glass is laminated on both the faces of the laminate 1, (iii) an organic component is removed from the laminate in a state where load is applied by a weight 3, then sintered, a glass ceramic board holding the restrained sheet is manufactured, (iV) the manufacturing method comprises a process for removing the restrained sheet from the board, (V) the glass content of the restrained green sheet 2 is bound with the glass ceramic green sheet during sintering, and its content does not substantially contract in a laminated face. |
