PROBLEM TO BE SOLVED: To provide a method of manufacturing printed wiring board in which a capacitor and an inductor element are formed in a printed wiring board in the manufacturing process of the wiring board, and by which the accuracy of the capacitance of the capacitor can be improved and the fluctuation of the capacitance can be reduced. SOLUTION: At the time of forming the capacitor and inductor element in the printed wiring board in the manufacturing process, the lower electrode 4 of the capacitor is formed by the subtractive method used for etching metal foil 2, and the upper electrode 7 of the capacitor is formed by the additive method or semi-additive method used for plating a metal. The area of the lower electrode 4 is made larger than that of the upper electrode 7. COPYRIGHT: (C)2005,JPO&NCIPI
