  • Patent number: 11456109
    Abstract: A coil component includes a magnetic laminate, a coil conductor having conductor patterns disposed in the magnetic laminate and extending around the coil axis, and a cover layer disposed on one end of the magnetic laminate in the direction along the coil axis. The magnetic laminate includes first magnetic layers disposed between the conductor patterns, and second magnetic layers disposed between the first magnetic layers. The first magnetic layers contain first soft magnetic metal particles having a first average particle size, the second magnetic layers contain second soft magnetic metal particles having a second average particle size, the cover layer contains third soft magnetic metal particles having a third average particle size larger than the second average particle size. In the direction perpendicular to the coil axis A, the first magnetic layers project outward from the second magnetic layers, and the second magnetic layers project outward from the cover layer.
