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.

Abstract translation: 提供一种线圈部件，其包括具有厚的线圈芯线和良好的电感特性并且能够使线圈电极的间距变窄的线圈。 线圈电极沿着线圈电极的卷绕轴线方向的布线包括多个第一金属销和多个第二金属销。 通过延长每个金属销，线圈电极的布线容易在金属销方向上伸长。 因此，线圈芯在金属销方向上容易增厚。 线圈电极的布线只能通过布置金属销而形成在金属销方向上。 因此，可以提供包括具有厚线圈芯线圈和良好的电感特性的线圈的线圈部件，并且能够使线圈电极的间距变窄。

Abstract: An inductor component includes an inductor electrode having two metal pins that form input and output terminals and a connecting conductor that connects one end of each of the metal pins to each other, the inductor electrode arranged such that other ends of the metal pins oppose each other, and a resin layer containing the inductor electrode such that other ends of the metal pins are exposed. The resin layer is formed having a single-layer structure. Variation in the characteristics of the inductor electrode can be reduced as compared to a case where the parts corresponding to the metal pins of the inductor electrode are formed as via conductors or through-hole conductors. Because the resin layer has a single-layer structure, stress acting on joint portions between the metal pins and the connecting conductor can be reduced, which makes it possible to improve the reliability of the inductor component.

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.
