    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 multilayer coil component includes an element assembly that has a first surface and second surfaces and extending in a direction orthogonal to the first surface, and terminal electrodes that has first electrode parts extending in a direction orthogonal to the first surface along the second surfaces. At least a portion of the first electrode parts of the terminal electrodes is disposed inside the element assembly. The element assembly is present between imaginary lines extending in a direction parallel to the first surface toward the second surfaces from a position farthest from the first surface in a direction orthogonal to the first surface in the first electrode parts positioned inside the element assembly and the first surface.
