A metallic printed board having layers including a metallic plate, an electric insulating layer and a metallic film, includes a plurality of insulating regions in the electric insulating layer. The insulating regions have different dielectric or thermal properties and are formed of a number of kinds of electric insulating materials having the different dielectric or thermal properties respectively. The insulating regions are arranged on an identical plane surface of the metallic plate. |
