Abstract
An earth electrode and a spiral pattern electrode are formed on both surfaces of a dielectric plate. One end of the pattern electrode is connected to the earth electrode. The width of the pattern electrode is made narrow in proportion to going from one end toward the other end. An area ratio S2/S1 is 0.15 or more when defining an area of the pattern electrode as S1, and an area of center portion where the pattern electrode is not formed as S2. A take-out electrode is drawn out from the pattern electrode with a distance from the one end of the pattern electrode. A chip type filter is manufactured by forming plural pattern electrodes on the dielectric plate, and coupling the pattern electrodes electromagnetically.
