    Abstract: In a coil component, a coil is disposed in the element body and has a pair of tip portions. A pair of external electrodes are disposed on an outer surface of the element body and respectively connected to the pair of tip portions. The element body includes a core portion including a shaft portion and a pair of side end portions. The shaft portion extends in a first direction, and the coil is wound around the shaft portion. The pair of side end portions are continuous with both ends of the shaft portion in the first direction. The shaft portion and the pair of side end portions are integrally formed of the same material. The shaft portion is covered with a resin molding portion. At least a part of the pair of side end portions is exposed from the resin molding portion.

    Abstract: In a coil 5 of a multilayer coil component 1, an end portion 6a of a turn 6 closest to a side surface 2e in the facing direction of the side surface 2e and a side surface 2f is connected to a first external electrode 3 and an end portion 11a of a turn 11 closest to the side surface 2f in the facing direction of the pair of side surfaces 2e and 2f is connected to a second external electrode 4. The area at which the turn 6 faces the second external electrode 4 and the area at which the turn 11 faces the first external electrode 3 are smaller than the area at which turns 7, 8, 9, and 10 other than the turn 6 and the turn 11 face the first external electrode 3 or the second external electrode 4.

    Abstract: A coil component includes an element body, a coil, a first terminal electrode, and a second terminal electrode. The coil has a coil axis extending in a direction in which a pair of side surfaces face each other. The first terminal electrode and the second terminal electrode have first electrode portions exposed on end surfaces and second electrode portions exposed on a main surface, respectively, and are not exposed on each of the pair of side surfaces. In a direction in which a pair of main surfaces face each other, a distance between each of ends of the first electrode portions on the main surface side and the main surface is larger than a distance between a top portion of the coil closest to the main surface and the main surface.

    Abstract: A coil includes a plurality of coil conductors. The coil includes a plurality of connection portions each at which adjacent coil conductors of the plurality of coil conductors are electrically connected to each other and the adjacent coil conductors overlap each other. The plurality of connection portions include a first connection portion and a second connection portion that is farther from an electrode portion on a main surface than the first connection portion. A second area where the adjacent coil conductors overlap each other in the second connection portion is larger than a first area where the adjacent coil conductors overlap each other in the first connection portion.
