Abstract
A coil component includes a core including a winding core portion and a first flange portion, a first wire and a second wire that are wound around the winding core portion in the same direction, and a first terminal electrode that is disposed on the first flange portion and that is connected to a first end portion of the first wire. The shape of an outer edge of the first terminal electrode includes a convex curve.
Claims2
A coil component comprising:
- a core including a winding core portion that extends in a length direction of the coil component and a first flange portion that is disposed on a first end portion of the winding core portion in the length direction;
- a first wire that is wound around the winding core portion;
- and
- a first terminal electrode that is disposed on a bottom surface of the first flange portion in a height direction of the coil component perpendicular to the length direction and that is connected to a first end portion of the first wire, and a shape of an outer edge of the first terminal electrode includes a convex curve,
- wherein the bottom surface of the first flange includes a first leg portion, and a first protruding portion formed on the first flange portion between the first leg portion and a first side surface, wherein the first leg portion and the first protruding portion project from the bottom surface of the first flange in the height direction of the coil component, with a height of the first protruding portion being less than a height of the first leg portion, and
- wherein the bottom surface of the first flange includes a second leg portion, and a second protruding portion formed on the first flange portion between the second leg portion and a second side surface, wherein the second leg portion and the second protruding portion project from the bottom surface of the first flange in the height direction of the coil component, with a height of the second protruding portion being less than a height of the second leg portion.
