PURPOSE:To provide a method for burning a ceramic substrate without causing the peeling of a conductor and sticking to a setter by contact of the surface conductor with the surface of the setter for burning in burning a low- temperature burnable circuit board material. CONSTITUTION:A low-temperature burnable ceramic material composed of one or two or more layers, printed with an Ag-based conductor paste having >=960 deg.C melting point and burnable at 800-1000 deg.C on at least one surface is burned. In the process, a setter for burning composed of a ceramic having >=5% porosity without softening at the burning temperature is used on the side of the surface conductor paste surface and then burned. |
