    Abstract: In a multilayer coil component, an end of a lower coil layer and an end of a connecting part are directly overlapped, and the end of the lower coil layer includes a contact edge positioned on a side of the connecting part and being in contact with the connecting part and a non-contact edge positioned on a side opposite to the connecting part and not being in contact with the connecting part. Then, the contact edge and the non-contact edge are not overlapped when viewed from a laminated direction. Consequently, a propagation distance of a crack becomes longer as compared with the case where an end face is parallel to the laminated direction, effectively suppressing advance of the crack. Suppressed advance of a crack in this manner makes the multilayer coil component provide a high component strength as a whole.

    Abstract: Each of internal conductors includes an annular portion with two end portions and an extension portion extending along the one end portion from the other end portion and separated from the one end portion. An edge of the one end portion and an edge of the other end portion oppose each other. The internal conductors include two first internal conductors and a second internal conductor located between the first internal conductors in a first direction. The one end portion of at least one first internal conductor includes a first portion overlapping the edges of the two end portions of the second internal conductor and a second portion overlapping a region between the edges of the two end portions of the second internal conductor, when viewed from the first direction. The second portion is recessed at a side opposite to the region, as compared with the first portion.

    Abstract: A coil includes a plurality of internal conductors that are electrically connected to each other and are disposed in an element body having magnetism. The plurality of internal conductors includes conductor portions that are separated from each other in a first direction and overlap each other when viewed from the first direction. At least one low-permeability layer is disposed along the conductor portions between the internal conductors adjacent to each other in the first direction. Permeability of the low-permeability layer is lower than permeability of the element body. The low-permeability layer includes a first portion contacting the internal conductors and at least one second portion separated from the internal conductors in the first direction, between the internal conductors adjacent to each other. The element body includes first element body regions that are interposed between the second portion and the internal conductors.

    Abstract: In a multilayer coil component, even when both pairs of ends of a first coil part and a second coil part are located at the same positions when viewed from the laminated direction and have the same shapes, a connecting part is connected only to a second end of the first coil part on the upper side in the laminated direction, and is connected only to a first end of the second coil part on the lower side in the laminated direction. Thus, a coil wound around along the laminated direction is structured without misaligning the positions of respective connecting parts. Consequently, the entire shapes of the respective coil parts can be designed to be the exact same shape, which makes it possible to reduce the number of types of coil part, saving labor and time for preparing many types of conductor patterns like the conventional type.

    Abstract translation: 在多层线圈部件中，即使当从层叠方向观察时第一线圈部和第二线圈部的两对端位于相同的位置并且具有相同的形状，连接部仅连接到第二端 的第一线圈部分在层叠方向上的上侧，并且仅在层叠方向的下侧仅连接到第二线圈部的第一端。 因此，沿着层叠方向缠绕的线圈被构造成不对准各连接部的位置。 因此，各线圈部件的整体形状可以被设计成完全相同的形状，这使得可以减少线圈部件的数量，节省了用于制备诸如常规类型的许多类型导体图案的人力和时间。
