等が優れたものとなっている。When using metal foil, the fluororesin layer in contact with the metal foil is most preferably made of a copolymer resin such as PFA or FEP (copolymer film, etc.), and is preferably made only of PTFE (straight tetrafluoride film, etc.). Next preferred. This is because it has the effect of improving the adhesion between the base material and the metal foil.The electrical laminate thus obtained uses the resin-impregnated base material as described above, and the Since the molding is done with a fluororesin layer interposed in between,
Adhesion between the eyebrows has improved. In addition, the base material contains tetrafluoroethylene resin, and a continuous fluororesin layer is formed between the base materials, and fluororesin layers are also formed on the outside of the resin-immersed base material on both outer surfaces, so high frequency It has excellent properties such as moisture resistance, water resistance, drilling workability, cutting workability, punching workability, and heat resistance.
