Abstract: In an electronic component, a multilayer body is formed by a plurality of stacked insulator layers. A coil includes at least one coil conductor layer provided on at least one of the insulator layers. External electrodes are embedded in a lateral surface of the multilayer body which is formed by a series of continuous perimeter edges of the plurality of insulator layers, and includes a plurality of stacked external conductor layers provided on the plurality of insulator layers. The external electrodes have different shapes. The external conductor layers and the first coil conductor, which are provided on the same insulator layer, are simultaneously formed by photolithography or printing.

Abstract: A noise filter includes a plurality of LC parallel resonant circuits having a plurality of coils which are connected in series and electrically connected to external electrodes at both ends thereof, and capacitors which are connected in parallel to the coils, respectively, and are disposed inside an insulator while being sequentially connected in tandem to signal wires. Resonance frequencies of the respective LC parallel resonant circuits are preferably different from each other. Further, a shield electrode is disposed between the coils, and the shield electrode also defines a capacitance-forming electrode for preventing magnetic coupling between the two coils.
