PROBLEM TO BE SOLVED: To provide a dielectrics changes electrical capacitance less at a high temperature, and a printed wiring board using the same. SOLUTION: A dielectrics 1 comprises an inorganic filler 2 whose dielectric constant is 100-1,000 and a resin material 3. The inorganic filler 2 is a fibrous material and covered with a conductive film. The printed wiring board comprises a conductor layer on an insulating board, and a capacitor 8 connected to the conductor layer. In the capacitor 8, the dielectrics 1 is interposed between a positive electrode plate 81 and a negative electrode plate 82. COPYRIGHT: (C)2004,JPO
