Abstract: A coil component includes a drum core that includes a winding core portion and a pair of flange portions formed at the ends of the winding core portion, electrodes that are included in the pair of flange portions, and first and second wires that are wound around the winding core portion and that include extended portions electrically connected to the electrodes. The flange portions are continuous with the winding core portion and have slopes that guide the extended portions to the electrodes.

Abstract: A bent shape that projects when viewed in an axis direction of a winding core part is given to each top surface of a first flange part and a second flange part of a drum-like core. The top surface and a lower principal surface of a plate-like core are closest to each other in a portion where a vertex of the bent shape is positioned.

Abstract: A coil component has a winding core part, and a plurality of wires that are wound on the winding core part to form a plurality of layers. The wires each include a conductor and a covering film that covers the conductor, an outer diameter of the wire of an n-th layer (“n” is an integer that is two or greater) is smaller than an outer diameter of the wire of an (n−1)th layer, an outer diameter of the conductor of the wire of the n-th layer is equal to an outer diameter of the conductor of the wire of the (n−1)th layer, and a thickness of the covering film of the wire of the n-th layer is smaller than a thickness of the covering film of the wire of the (n−1)th layer.

Abstract: A coil component includes a core including a winding core portion and a pair of flange portions provided at both ends of the winding core portion, electrode portions provided in the flange portions, a wire wound around the winding core portion, and a magnetic plate fixed to the flange portions. The magnetic plate includes an annular first planar portion, a second planar portion that is located inside the inner circumference of the first planar portion and has a step between the first and the second planar portions, and a connection surface portion connecting the inner circumference of the first planar portion to the outer circumference of the second planar portion. The connection surface portion is configured by annularly disposing at least three slopes inclined with respect to the direction orthogonal to the first planar portion and has chamfered portions each being disposed between adjacent slopes.
