    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.

    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 common-mode choke coil is configured such that in one turn of a stranded portion, a number of times a first wire is disposed outside a second wire on a first side surface of a core is equal to a number of times the second wire is disposed outside the first wire on a second side surface that is opposite to the first side surface. Also, a number of times the first wire is disposed outside the second wire on a top surface of the core is equal to a number of times the second wire is disposed outside the first wire on a bottom surface that is opposite to the top surface.
