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: An electronic component includes an element body including a first principal surface and a second principal surface opposing each other, and first and second external electrodes disposed on the first principal surface and separated from each other. The element body includes a first region including the first principal surface and a second region located between the first region and the second principal surface. The first region includes a portion located between the first and second external electrodes. The portion included in the first region is in contact with the first and second external electrodes. When viewed in a direction in which the first principal surface and the second principal surface oppose each other, the portion included in the first region covers an end of each of the first and second external electrodes. The first region has hardness greater than that of the second region.
