摘要： A method for manufacturing an inductor is performed in such a manner that the surface of a metal wire provided with an insulating film thereon is coated with a thermal melting resin. The thickness of the thermal melting resin is, for example, approximately 1 μm. As the thermal melting resin, a thermoplastic resin or a thermosetting resin, such as a polyimide resin or an epoxy resin, containing 85 wt % of a powdered ferrite is used. This coated metal wire is densely wound to form a solenoid-type coil conductor. Next, the thermal melting resin is softened by a heat treatment at, for example, 180° C. and is then solidified by spontaneous cooling. Accordingly, the portions of the coil conductor adjacent to each other are bonded together by the thermal melting resin.

摘要： A method for efficiently and economically manufacturing an inductor using a resin based magnetic material, and a highly reliable inductor that is manufactured by the method, produces a unique inductor including a molded magnetic material member. An inner conductor is disposed in the molded magnetic material member and is exposed at a surface of the molded magnetic material member. The molded magnetic material member is formed using the resin based magnetic material in which a component that functions as nuclei for applying electroless plating is blended, followed by forming a selectively coated molded body so that the area not provided with external electrodes on the surface of the molded magnetic material member is covered with an insulating resin and applying electroless plating on the molded magnetic material member (selectively coated molded body), thereby eliminating use of a resist agent that is required in the conventional manufacturing method, as well as a resist agent removing step with an alkali and solvent and a removing step of the electroless plating film with an acid, by forming the electroless plating film as the external electrodes on the desired area.

摘要： An electronic component includes an internal conductor (conductor coil) made of a metal that is embedded in a molded body. The molded body is formed by molding a ferrite resin into a fixed shape, such that at least a portion of the internal conductor is exposed on the surface of the molded body, and external electrodes, which are connected to the internal conductor, are provided in a fixed area, including the exposed portion of the internal conductor, on the surface of the molded body. The electronic component is manufactured by depositing palladium at a density of about 0.5 &mgr;g/cm2 to about 1.5 &mgr;g/cm2 in the area in which the internal conductor is not exposed on the molded body, and at a density of about 0.05 &mgr;g/cm2 to about 0.3 &mgr;g/cm2 on the internal conductor exposed on the surface of the molded body. The external electrodes are formed via a process of forming a metal film (electroless plating film) on the surface of the molded body by conducting electroless plating.

摘要： A noise filter includes a capacitor having a hot side input terminal, a hot side output terminal, a ground side input terminal, and a ground side output terminal. A circuit board includes a hot side input electrode connected to the hot side input terminal, a hot side output electrode connected to the hot side output terminal, a ground side input electrode connected to the ground side input terminal, and a ground side output electrode connected to the ground side output terminal. The impedance of the ground side input terminal seen from the ground side output electrode is larger than both the impedance of the ground side output terminal seen from the ground side output electrode and the impedance of the hot side output terminal seen from the ground side output electrode. For this purpose, a stray capacitance formed between the ground side input electrode and the ground side output electrode is reduced by increasing a gap therebetween. Accordingly, excellent noise-reducing characteristics are provided.
