摘要： A method of manufacturing an electronic component provides a wide area which can be used for forming elements on the surface of a mother substrate and effectively produces an electronic component having excellent performance characteristics. At least a portion of the mother substrate is cut by using a blade having a shape in which a portion thereof butted against the boundary (shoulder) between the electrode arrangement surface and the cut end surface of the mother substrate or a portion which becomes the boundary (shoulder) is inclined at a predetermined angle to form an inclined surface at the boundary (shoulder) or the portion which becomes the boundary (shoulder) so as to expose a part of an electrode at the inclined surface.

摘要： There is provided a chip type filter which can be made compact, allows the matching of input/output impedance, and has preferable characteristics. A ground electrode is formed on one side of a dielectric substrate, and spiral-shaped pattern electrodes are formed on the other side. Input/output electrodes are led out from intermediate portions of the pattern electrodes. Curved portions are formed between the input/output electrodes and the ends of the pattern electrodes. The ends of the pattern electrodes are positioned close to each other. Protective layers are formed on the ground electrode and pattern electrodes, which are laminated and integrated to form external electrodes. The ends of the pattern electrodes and the ground electrode are connected by one of the external electrodes.

摘要： 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.
