PROBLEM TO BE SOLVED: To provide a small sized filter that is applicable to high frequencies and has a small loss while being less affected by other electronic components. SOLUTION: Capacitors 2, 3 and inductive elements 4, 5, 6 are mounted on a printed circuit board 1 and the capacitors and the inductive elements are connected through conductive patterns 7, 8, 9, 10, 11. Then at least each inductive element is realized by a chip component that directly connect to other component or wires with terminals directly formed at both ends of the component. The filter is configured by mounting inductive element type resonators 202, 203 and passive elements 204, 205, 206 on a printed circuit board 201, and a chip component is adopted for each of the inductive element type resonators 202, 203 to connect directly to other component and wires with the terminal directly formed at both ends of the component.
