A coil is provided in the element body and wound helically. Two external electrodes are provided in the element body and electrically connected to the coil. One of the external electrodes is formed over one of the end surfaces and the bottom surface while the other external electrode is formed over the other of the end surfaces and the bottom surface. The coil is formed such that an axial direction thereof is along the two end surfaces and the bottom surface. The coil includes a coil wiring wound along a plane orthogonal to the axial direction, and the aspect ratio of the coil wiring is 1.0 or more and less than 8.0.

摘要： A method of manufacturing an inductor includes a lamination step, a division step, a firing step, and a plating step. In the lamination step, a laminate including an insulator, a coil body, and external electrodes is formed. That is, in the lamination step, insulating layers having wide filling conductors, insulating layers having narrow filling conductors, and conductor patterns having external electrode patterns are laminated. As a result, the conductor patterns form the coil body, and the wide filling conductors, the narrow filling conductors, and the external electrode patterns form the external electrodes. The narrow filling conductors have a width that is less than the widths of the wide filling conductors and the external electrode patterns, and recesses and projections are provided in the external electrodes.

摘要： A ceramic electronic component includes a ferrite material magnetic body part and a Cu conductive part, the ferrite containing 20 to 48% trivalent Fe in terms of Fe2O3 and divalent Ni. The ferrite can contain Mn so that it is less than 50% of the total of Fe and Mn in terms of Mn2O3 and Fe2O3. The magnetic and conductive parts are co-fired at a pressure not exceeding the equilibrium oxygen partial pressure of Cu—Cu2O thereby ensuring insulating performance and favorable electrical characteristics.

摘要： [Problem] When a core is configured by injection-molding a mixture including a soft magnetic powder and a thermoplastic resin and a reactor is manufactured by integrating a coil in a state where the coil is embedded in the inner portion of core, positional misalignment or deformation of coil at the time of molding the core can be effectively prevented, and the core can be favorably molded using an injection molding method.[Solution Means] A reactor 15 is manufactured through a step A of encasing a coil 10 configured by winding a wire in a state where an insulating layer is interposed between the wires with an electrically insulating resin to mold an encased coil body 24, and a step of molding a core 16 by injection-molding a mixture including a soft magnetic powder and a thermoplastic resin in a state where the encased coil body 24 is enclosed. In addition, the injection molding of the core 16 is performed so as to be divided into a step in which a primary molded body 16-1 having a container shape alone is molded and a step in which a secondary molded body 16-2 is molded in a state where the encased coil body 24 is set along with the primary molded body 16-1.
