1. 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, the winding core portion including a first curved portion that is formed at a connection between a bottom surface of the winding core portion and the first flange portion, the winding core portion includes a third curved portion that is formed at a connection between an upper surface of the winding core portion and the first flange portion, and a length of the first curved portion in the length direction is longer than a length of the third curved portion in the length direction;
a first wire and a second wire that are wound around the winding core portion in the same direction;
a first terminal electrode that is disposed on a bottom part 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 second terminal electrode that is disposed on the bottom part of the first flange portion and that is connected to a first end portion of the second wire,
wherein a ratio of a length of the first curved portion in the height direction to a distance in the height direction between the bottom surface of the winding core portion and the first terminal electrode is from 20% to 60% in a section of the winding core portion that passes through a center of the winding core portion and that is along a plane extending in the length direction and in the height direction.
