Abstract
There is disclosed a method of producing a ceramic multilayer substrate by laminating a plurality of glass-ceramic green sheets made of a glass-ceramic containing an organic binder and a plasticizer to form a laminate; and firing the laminate; further comprising: applying to or overlaying on the surfaces of the glass-ceramic green sheets inorganic compositions, the sintering temperature of the inorganic compositions being higher than that of the glass-ceramic green sheets; laminating a plurality of the glass-ceramic green sheets having the inorganic compositions applied to or overlaid on the surfaces of the glass-ceramic green sheets respectively, to form a part of the laminate; and laminating a plurality of the glass-ceramic green sheets to form the other part of the laminate.
