Conventional printed circuit boards had a problem of being inferior in heat-radiation characteristic, and metal-core printed circuit boards adopted to improve the heat-radiation characteristic had problems in having low rigidity and a tendency to bend. The ductility of the metal can be obstructed, and the metal protected; by covering substantially the whole area of the front and back sides of the metal core, consisting of metal as the main material, with a first ceramic film and a second ceramic film that obstruct the ductility of the aforementioned metal-core; and covering each of the ceramic films with insulated resin films, to cover the fragility of these ceramics.

The likelihood of exfoliation of a sealing resin layer at a pad electrode part is reduced so that the reliability of a circuit apparatus is improved. A circuit apparatus includes a wiring layer, a gold plating layer, an insulating resin layer, a circuit element, a conductive member and sealing resin layer. The gold plating layer is formed in an wiring layer area for the pad electrode. The surface outside the area is roughened. The insulating resin layer is formed so as to cover the wiring layer and to have an opening in an area in which the pad electrode is formed. The circuit element is mounted on a predetermined area on the insulating resin layer. The sealing resin layer is formed on the insulating resin layer so as to entirely cover the circuit element and the opening for the pad electrode. The sealing resin layer, in the area for the pad electrode, is in contact with the gold plating layer and the wiring layer.

In a manufacturing method of a hybrid integrated circuit device 10 according to the present invention, a first dummy pattern D1 is provided on a first wiring layer 18A. Furthermore, a second dummy pattern D2 is provided on a second wiring layer 18B. The first dummy pattern D1 and the second dummy pattern D2 are connected through a connection part 25 which penetrates an insulation layer 17. Hence, heat dissipation through a dummy pattern can be actively performed. In addition, even in the cases where a multi-layered wiring is formed, it is possible to provide a circuit device which can secure a heat dissipation property.

Provided are a circuit board with enhanced moisture resist and the method of manufacturing the circuit board, and a circuit device and a method of manufacturing the circuit device. A circuit board of the present invention includes: a substrate; wirings formed on the main surface of the substrate; a cover layer covering the wirings excluding the regions to be connectors; back electrodes formed on the bottom surface of the substrate; and through-hole electrodes formed so as to penetrate the substrate, and thereby connecting the wirings and the back electrodes. On surfaces of each of the wirings in this circuit board, convex portions on the periphery of the substrate are set larger in width than convex portions in a center portion of the substrate. With this configuration, adhesion reliability between the wirings and the cover layer under a thermal cycle load can be enhanced.
