摘要： An un-sintered multi-layered body includes a first ceramic layer having a surface, a conductor provided on the surface of the first ceramic layer, an insulator provided on the surface of the first ceramic layer and covering an end of the conductor, and a second ceramic layer provided on the conductor and the insulator. The un-sintered multi-layered body is baked at a temperature at which the first ceramic layer can be sintered but the second ceramic layer cannot be sintered. After the un-sintered multi-layered body is baked, the second ceramic layer is removed, thereby providing a multi-layered ceramic substrate. The insulator has a thickness not smaller than 10 μm and not larger than 40 μm. This method makes the insulator dense and allows the conductor to be formed easily.
