  • Patent number: 10418168
    Abstract: A small-sized inductor with desired characteristics is provided. An inductor 1a includes a resin layer 3 and an inductor electrode 6, which includes an inner winding portion 6a and an outer winding portion 6b. The inner winding portion 6a and the outer winding portion 6b forming the inductor electrode 6 include the metal pins 7a to 7d and the wiring boards 8a to 8d. Here, the inner winding portion 6a and the outer winding portion 6b include the metal pins 7a to 7d and the wiring boards 8a to 8d, which have lower specific resistance than conductive paste or plating. This structure thus can reduce the resistance of the entirety of the inductor electrode 6, and improve the characteristics of the inductor 1a. The inductor 1a can reduce its size by including the inductor electrode 6 wound to have a multiplex winding structure.

  • Patent number: 10410782
    Abstract: A coil component is provided with only first and second columnar conductors that are a part of a coil electrode. This can simplify the manufacturing process and reduce the cost of the coil component. A wiring substrate is provided with substrate-side wiring electrode traces that form the remaining part of the coil electrode. In the process of forming the wiring substrate using a substrate forming technique commonly used, the substrate-side wiring electrode traces can be easily formed together with other wiring electrodes. Therefore, when the coil electrode is configured to be formed by placing the coil component on the wiring substrate, a coil module including the coil component can be inexpensively manufactured.

  • Patent number: 10403431
    Abstract: A coil component that includes a coil having a thick coil core and good inductance characteristics and is able to narrow the pitch of a coil electrode is provided. The wiring of a coil electrode in a direction across the direction of a winding axis of the coil electrode includes a plurality of first metal pins and a plurality of second metal pins. By elongating each metal pin, the wiring of the coil electrode is easily elongated in a metal pin direction. Thus, a coil core is easily thickened in the metal pin direction. The wiring of the coil electrode can be formed in the metal pin direction only by arranging the metal pins. Thus, it is possible to provide a coil component that includes a coil having the thick coil core and good inductance characteristics and is able to narrow the pitch of the coil electrode.
