ラス布の織回が金属箔表面に浮き出し、表面粗度が大と
なりファインパターン化に支障をきたす問題があった。Conventionally, a laminated board in which a core portion is a nonwoven fabric and a surface portion is made of a glass cloth and resin is impregnated with a resin, since both the nonwoven fabric and the glass cloth use a resin having the same curing rate, the glass cloth below the metal foil is used. This causes the problem that the weaving time is raised on the surface of the metal foil, and the surface roughness becomes large, which hinders fine pattern formation.

用積層板を提供することにある。As described in the related art, there is a problem in this type of conventional laminated plate that the surface roughness of the laminated plate is large. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the related art, and an object of the present invention is to provide an electric laminate having a small surface roughness.

とができたもので、以下本発明を詳細に説明する。The present invention arranges a long glass cloth impregnated with a resin having a faster curing speed than the resin on the upper and lower surfaces of a long nonwoven fabric impregnated with an inorganic filler, and further arranges a long metal foil on the upper surface and / or the lower surface. The laminated body for electricity is characterized in that the laminated body is heated under no pressure and cut to the required dimensions, so that the resin under the metal foil hardens quickly and hardens, reducing the surface roughness. The present invention will be described in detail below.

Polybutadiene resin, thermosetting polyphenylene oxide resin, fluorocarbon resin, etc. can be used alone, modified, or a mixture, but the curing speed of the resin impregnated in the glass cloth should be faster than the resin impregnated in the nonwoven fabric. is necessary. As a means for this, the addition of a curing agent, a cross-linking agent, a reaction initiator, and the like to the nonwoven fabric impregnating resin is eliminated, but even if it is used, a means for reducing the amount compared to the glass cloth impregnating resin is effective. The difference in curing speed is desirably 1 minute or more. For this reason, a curing agent, a cross-linking agent, a reaction initiator and the like are added to the glass cloth impregnating resin in an amount of 0.5 to 1.5 with respect to 100 parts by weight of the resin (hereinafter simply referred to as “parts”). It is preferable to add a part.

である。As the inorganic filler, calcium carbonate, aluminum hydroxide, talc, alumina, silica, magnesium carbonate and the like can be used, and 1 to 200 parts can be added to 100 parts of the resin. The nonwoven fabric is made of glass fiber, organic fiber, or the like, and any nonwoven fabric including spunbonded nonwoven fabric, glass paper, or the like can be used. The glass cloth is not particularly limited, and a commonly used glass cloth can be used as it is. As the metal foil, a single or alloy such as copper, aluminum, iron, nickel, and zinc can be used, and an adhesive layer can be provided on the adhesive surface as needed. The heating can be selected depending on the resin used, and the pressure is non-pressure only due to the weight of the laminate.
