Abstract: A winding-type coil component includes a first wire and a second wire having a twisted wire portion where the first wire and the second wire are twisted together. Switching positions of the first wire and the second wire in the twisted wire portion are shifted in a circumferential direction of a winding core portion every turn.

Abstract: A coil component has an outer electrode include a bottom-surface electrode portion disposed along a bottom surface of a component body and an end-surface electrode portion disposed along an end surface of the component body so as to be continuous with the bottom-surface electrode portion. The adhesive strength of the bottom-surface electrode portion with respect to the component body is lower than that of the end-surface electrode portion with respect to the component body.

Abstract: First and second wires form a wire assembly by being wound around a winding core portion together. The wire assembly includes a twisted wire portion, an inner layer portion, an outer layer portion, a plurality of outward transition portions, and an inward transition portion. The outer layer portion includes a first outer layer portion which is connected to one of the outward transition portions extending from an intermediate position of the inner layer portion and connected to the inward transition portion. The inward transition portion extends to an intermediate position of the inner layer 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.

Abstract: A flange portion includes a projecting surface that is positioned in a leading end of a projection projecting toward a mounting substrate and that faces the mounting substrate, and a principal surface that extends in a direction crossing the projecting surface and that faces a direction in which the pair of flange portions are aligned. A metal terminal includes a mounting portion opposed to the projecting surface and an end surface portion opposed to the principal surface. An angle θ between the mounting portion and the end surface portion satisfies the relationship 85 degrees≤θ

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.
