のではなかった。2. Description of the Related Art Conventionally, a laminated plate is formed by integrally laminating a laminated body composed of resin-impregnated paper or resin-impregnated woven fabric and a metal foil, but since it is hard, it cannot be bent. On the other hand, the flexible plate was not stiff and so-called L-shaped processing could not be performed. Therefore, a laminated plate in which a resin-impregnated woven fabric is arranged and formed on the upper surface and / or the lower surface of the resin-impregnated nonwoven fabric and the workability is improved to some extent, but it is not yet satisfactory.

意である。The base material of the resin-impregnated base material excluding the non-woven fabric used in the present invention is an inorganic fiber such as glass, ceramic or asbestos, vinyl alcohol, polyimide, polyethylene terephthalate, polybutylene terephthalate, polyamide or polyphenylene sulfide. Woven fabrics, papers and the like made of organic fibers such as polyphenylene oxide and fluororesin and natural fibers such as cotton. As the resin with which the base material is impregnated, phenol, epoxy, unsaturated polyester,
Polyimide, polyamide, polyphenylene oxide,
Polyphenylene sulfide, polybutadiene, fluororesin, etc. alone, modified products, and mixtures are used, and if necessary, talc, clay, calcium carbonate, aluminum hydroxide, inorganic powder filler such as silica, and glass. fiber,
Fibrous fillers such as asbestos fibers, pulp fibers, synthetic fibers and ceramic fibers can be added. Further, the resin may be impregnated only with the same resin, but a plurality of impregnations such as primary impregnation and secondary impregnation with the same type resin or different type resin may be performed to make the impregnation more uniform. Thus, after impregnating the base material with the resin, it is dried by heating or the like, if necessary, to obtain a resin-impregnated base material. The required number of resin-impregnated base materials can be used as needed. As the resin-impregnated non-woven fabric, the same material as the resin-impregnated base material can be used as it is as the non-woven fabric. The resin used for the resin-impregnated base material can be used as it is as the resin for impregnating the non-woven fabric, and the resin-impregnated non-woven fabric can be obtained by drying it by heating or the like if necessary. The required number of resin-impregnated nonwoven fabrics can be used as needed. Copper as the metal foil,
Aluminium, brass, nickel, iron etc. alone, alloy,
A composite foil is used, and an adhesive layer can be provided on one side of the metal foil if necessary. Thus, the resin-impregnated non-woven fabric is arranged on the upper surface and / or the lower surface of the resin-impregnated base material,
Further, the above-mentioned metal foil is arranged and formed as an outermost layer to obtain a laminated plate. The unifying means is not particularly limited and is arbitrary.
