Abstract: A coil component is provided with first wire and second wires that are wound around a winding core. nth turns of the first and second wires are wound around a surface of the winding core in this order in parallel and form a first winding layer. Each of n+1th and subsequent turns of the second wire is wound around the surface of the winding core so as to be parallel to a previous turn of the second wire and form the first winding layer. Each of n+1th and subsequent turns of the first wire is wound on the first winding layer so as to be fitted into a valley of the first winding layer formed by the same and previous turns of the second wire and form a second winding layer. The same turns of the first and second wires are adjacent to each other at each turn.

Abstract: 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.

Abstract: 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.
