    Abstract: A coil component includes a drum-shaped core including a winding core portion and first and second flange portions that are provided respectively at both end portions of the winding core portion, and a plate-shaped core bridging the first and second flange portions. The first flange portion has a top surface opposed to one principal surface of the plate-shaped core, and a resin containing magnetic powder having a particle size of not less than about 50 nm and not more than about 1000 nm is present between the principal surface of the plate-shaped core and the top surface of the first flange portion.

    Abstract: A coil component comprising a core having a winding core part, and a coil wound around the winding core part and including a plurality of wires. The coil includes a twisted wire portion in which the plurality of wires is twisted together. The twisted wire portion includes a bank region including a first layer wound multiple turns continuously around the winding core part and a second layer wound on the first layer continuously from the first layer. The bank region is sparsely wound with the number of turns of the second layer reduced by two or more as compared to the number of turns of the first layer.

    Abstract: A winding core includes, for example, four planes, that is, a top surface, a bottom surface, a first side surface, and a second side surface around its central axis. A first wire and a second wire are wound around the winding core in the same direction and have a twisted section. In the twisted section in a plurality of turns at the top surface, bottom surface, first side surface, and second side surface, both the first wire and the second wire are in close contact with each of the ridges between the top surface, bottom surface, first side surface, and second side surface.

    Abstract: A coil component includes a core including a winding core portion, a first flange portion, and a second flange portion, a first wire and a second wire that are wound around the winding core portion in the same direction and that form a winding portion, a first terminal electrode and a second terminal electrode that are disposed on the first flange portion, and a third terminal electrode and a fourth terminal electrode that are disposed on the second flange portion. A length of the winding portion along a bottom surface of the winding core portion is shorter than a length of the winding portion along an upper surface of the winding core portion.

    Abstract: A coil component comprising a core including a winding core having a shape extending in a constant direction, a first flange disposed at a first end in an extending direction of the winding core, and a second flange disposed at a second end in the extending direction of the winding core; first and second electrodes disposed on the first flange; third and fourth electrodes disposed on the second flange; and a coil including a first wire wound around the winding core and electrically connected to the first and third electrodes, and a second wire electrically connected to the second and fourth electrodes. The first and second flanges each have an inner surface facing the winding core, an outer surface facing toward the side opposite to the inner surface, a lower surface connecting the inner and outer surfaces, and an upper surface facing the side opposite to the lower surface.
