Abstract:
1. A coil component comprising: a core comprising a winding portion, and first and second flanges disposed one on either end of the winding portion; a winding wound about the winding portion; and terminal electrodes disposed on the first flange; wherein the first flange has a bottom surface constituting a first endface of the core, and a peripheral surface extending toward a second endface of the core from a peripheral edge of the bottom surface; wherein the bottom surface is formed in an octagonal shape when viewed along a line connecting the first flange and the second flange and has a first omitted side, second omitted side, third omitted side, and fourth omitted side configured by chamfering or cutting an imaginary square-shaped bottom surface at a position corresponding to a first corner located on a first end of a first side forming the bottom surface, a position corresponding to a second corner located on a first end of a second side opposing the first side, a position corresponding to a third corner located on a second end of the first side, and a position corresponding to a fourth corner located on a second end of the second side; wherein the peripheral surface has surfaces corresponding to all sides of the octagonal bottom surface, including a first peripheral surface extending from the first side, a second peripheral surface extending from the second side, a first omitted peripheral surface extending from the first omitted side adjacent to the first peripheral surface, a second omitted peripheral surface extending from the second omitted side adjacent to the second peripheral surface, a third omitted peripheral surface extending from the third omitted side adjacent to the first peripheral surface, and a fourth omitted peripheral surface extending from the fourth omitted side adjacent to the second peripheral surface; wherein the terminal electrodes comprise a first terminal electrode and a second terminal electrode, the first terminal electrode being disposed across the first omitted peripheral surface, a part of the bottom surface covering at least a region linking an entire length of the first omitted side to an entire length of the third omitted side, and the third omitted peripheral surface, and the second terminal electrode being disposed across the second omitted peripheral surface, a part of the bottom surface covering at least a region linking an entire length of the second omitted side to an entire length of the fourth omitted side, and the fourth omitted peripheral surface; and wherein the winding has a first end electrically connected to the first terminal electrode on the first omitted peripheral surface, and has a second end electrically connected to the second terminal electrode on the second omitted peripheral surface.
