<p>PURPOSE:To execute molding, processing, metallizing printing and the printing of an insulating layer efficiently by printing a metallized wiring pattern and an external terminal to a gree ceramic sheet not baked and forming an external terminal section by a hot press. CONSTITUTION:A slurry-like ceramic raw material is flowed through a tape caster and a tape is molded, and the ceramic green sheet 1 is obtained. Through- holes 3 reaching one surface from the other surface are punched, and an inner surface is printed by using metallizing ink. A back pattern 6 is metallizing-printed, the sheet 1 is turned over and a surface pattern 7 is metallize-printed, and an insulating layer pattern 12 is formed so as to coat the intermediate section of a peripheral pattern 10. The sheet is molded by a press so that the surface is indented and the back is projected through heating and pressing, a snap groove is formed, the sheet is baked in a reducing atmosphere, and a metallic conductor layer not coated is plated.</p> |
