PROBLEM TO BE SOLVED: To provide dielectric material wherein electric insulation in thickness direction can be ensured when conductive filler density is increased for increasing permittivity, and provide a printed wiring board including a capacitor of high capacity mass density and low loss. SOLUTION: Electrodes 4, 5 are arranged on both surfaces of a planar dielectric material 3 wherein planar conductive filler 1 is contained in insulating resin 2, and the material 3 is made to function as a capacitor. The conductive filler 1 is orientated in such a manner that plate surface of the planar conductive filler 1 and plate surface of the planar dielectric material 3 become almost parallel with each other.
