摘要: A metal-foil-clad composite ceramic board produced by impregnating a sintered substrate (II) of an inorganic continuously porous body (I) having true porosity 12 to 50% and open at least 10%, with thermosetting resin (R) under vacuum, form resin-impregnated (IIR), stacking metal foil on the (IIR) press-forming resultant laminate, wherein stacked has 10-point average surface roughness Rz 10 μm or less, have substantially no adhesive layer therebetween thickness less therebetween.
