Abstract
A method of making a multi-layered ceramic substrate which includes the steps of laminating a desired number of green sheets each being made of glass ceramics containing at least an organic binder and a solvent and each having a pattern of electrodes formed thereon by the use of an electroconductive paste, to thereby provide a green sheet laminate, The electrodes on opposite surfaces or an entire surface layer of the green sheet laminate are subsequently printed with a paste comprising an inorganic component added with at least an organic binder containing a Zn composition. On each surface of the laminate printed with the paste of the Zn composition, a green sheet made of an inorganic composition incapable of being sintered at a temperature of crystallization of the glass ceramics is then laminated thereby providing a laminate plate which is subsequently fired. After the firing, both of the inorganic composition incapable of firing sintered and the Zn composition are removed from the opposite surfaces of the laminate. The paste of the Zn composition may contains a main component selected from the group consisting of Zn, ZnO, Zn(OH).sub.2, ZnAl.sub.2 O.sub.4, and ZnCO.sub.3.
