摘要： A coil component includes a first core, a second core, a lead wire, an outside mark, and an inside mark. The first core includes a winding portion and a pair of core ends. The second core connects a pair of the core ends and includes an inside surface and an outside surface. The lead wire is wound around the winding portion. The outside mark is formed on the outside surface of the second core and designed to change its arrangement at the time of rotating the second core by 90 degrees in a rotational direction whose central axis is along a normal direction of the outside surface. The inside mark with undulation is formed on the inside surface of the second core and designed to change its arrangement at the time of rotating the second core by 90 degrees in the rotational direction.

摘要： An inductor includes: an element body having a pair of end surfaces facing each other, and a side surface extending in a facing direction of the pair of end surfaces to connect the pair of end surfaces; and a through conductor disposed inside the element body and extending in the facing direction. The element body includes a first portion surrounding the through conductor, and a second portion positioned outward of the first portion, when viewed in the facing direction. The first portion is disposed spaced from the side surface. The first portion has a porosity higher than a porosity of the second portion.

摘要： A multilayer inductor includes: an element body having a pair of end surfaces facing each other, and a side surface extending in a facing direction of the pair of end surfaces in such a way as to connect the pair of end surfaces; and a through conductor disposed inside the element body and extending in the facing direction. The element body includes a first portion surrounding the through conductor and a second portion positioned outward of the first portion, when viewed in the facing direction. The first portion is disposed spaced from the side surface. The first portion and the second portion have different magnetic permeabilities from each other.

摘要： A coil device includes a magnetic core and terminal electrodes. The terminal electrodes include attachment pieces, wire connection rising pieces, connection pieces, and fillet forming pieces. The wire connection rising pieces are integrally risen from one ends in a longitudinal direction of the attachment pieces along a side surface in the X-axis direction of a flange. The connection pieces are integrally formed with upper end sides of the wire connection rising pieces and have welded balls connected to lead parts of a wire by laser welding. The fillet forming pieces are integrally risen from one ends in a lateral direction crossing the longitudinal direction of the attachment pieces along a side surface in the Y-axis direction of the flange. Laser shielding members are arranged between the welded balls and the flange of a magnetic core.
