PROBLEM TO BE SOLVED: To provide a circuit board with filter having superiority in downsizing and densifying of a circuit board area. SOLUTION: A lower electrode layer 12, a dielectric layer 13, and an upper electrode layer 14 are formed on an insulated board 11 by printing and burning, thereby composing a layered capacitor C. Also, a chipped ferrite element 19 which is an inductance component is mounted on the board 11. Alternatively, instead of the chipped ferrite, a ferrite layer having a spiral conductor (spiral inductor) therein is formed on the board by printing and burning. COPYRIGHT: (C)2003,JPO
