Abstract: PURPOSE:To manufacture a low cost ceramic wiring board wherein the adhesion of conductor layers is excellent and the reliability of through hole is high by roughening a ceramic substrate surface by physical ion etching method, before a conductor layer is formed. CONSTITUTION:A hole 2 for a through hole is formed on a baked alumina substrate 1 with laser. This substrate 1 is arranged in a sputtering chamber, and subjected to sputtering under Ar gas pressure of 3X10<-3>Torr.

The substrate 1 is dipped in sensitizing and activating treatment solution in turn, and the seeding of palladium on the exposed part of the substrate 1 is performed. By dipping this substrate in chemical copper plating solution, a copper layer of about 1mum thick is formed. Copper sulfate electroplating is performed thereon, and then the plating resist film is exfoliated. On an obtained circuit on the substrate surface, resistive paste of glaze system is spread in a desired pattern by screen printing. By baking this under N2 atmosphere, resistor 4 is formed, and a wiring board having a through hole is obtained. Thereby the adhesion strength of the conducting layer 4 can be improved.

Abstract: PURPOSE:To easily mold even a shape having modified surface and large in the difference in level of unevenness by directly bonding a skin layer to a base material foam in a state being the substantially same size as the cell size of a foam layer receiving no hot pressing. CONSTITUTION:A heating mold 3 heated to the m.p. of the base material resin of a thermoplastic synthetic resin non-crosslinked open-cell foam 1 or higher is allowed to approach the foam 1 to be pressed thereto. When the foam is heated to its m.p. or higher, said foam is melted to become extremely well in flowabiltiy. Since air in the cells of the foam is heated to its m.p. or higher, said foam is melted to become extremely well in flowabiltiy. Since air in the cells of the foam escapes through the communicating gaps of open cells, molten and fluidized cell films easily form a skin layer to advance in the advance direction of the heating mold 3. When there is difference in level in a molded product, one different in level in a molded product, one different in the thickness of the skin layer every steps is formed. The surface of the obtained molded body has no rough feel due to cell films and is subjected to surface finish feeling smooth and pleasant. When an embossed pattern of every kind is applied to the surface of the heating mold, a fine embossed pattern can be applied to the surface of the molded product.
