PROBLEM TO BE SOLVED: To obtain a metal-plated laminated board which is excellent in surface smoothness, high in galvanic corrosion resistance, and excellent in drilling processability and capable of coping with wiring of high density. SOLUTION: Thermosetting resin particles which are solid at normal temperatures and uncured are dispersed into inorganic fiber and bonded together with curing binder resin into a resin sheet, and the resin sheet is sandwiched in between a metal base 1 and a wiring board 3, and the above laminate is thermocompressed. The resin sheet. is formed through such a manner that slurry which comprises inorganic fiber and thermosetting resin particles that are solid at normal temperatures and uncured is formed into a sheet, curing binder resin is applied onto the sheet, and the sheet is dried up by heating to cure the curing binder resin. |
