Coil component

A coil component comprising:

• a drum-shaped core including a winding core portion and first and second flange portions disposed at respective opposing first and second end portions of the winding core portion;
• and
• first and second wires that are wound around the winding core portion and are not electrically connected to each other, wherein
• the first and second wires form a wire assembly by being wound around the winding core portion together,
• the wire assembly includes a twisted wire portion at which the first and second wires are twisted together, an inner layer portion that in contact is with and wound around a circumferential surface of the winding core portion, an outer layer portion wound around an outer circumference of the inner layer portion, a plurality of outward transition portions each extending from the inner layer portion to the outer layer portion, and a plurality of inward transition portions each extending from the outer layer portion to the inner layer portion,
• the outer layer portion includes a plurality of first outer layer portions that are each connected to a respective one of the plurality of outward transition portions extending from a position of the inner layer portion that is between end portions of the inner layer portion in a winding axial direction and connected to a respective one of the plurality of inward transition portions extending to another position of the inner layer portion that is between the end portions of the inner layer portion in the winding axial direction, and
• a number of turns in a range of the inner layer portion from one inward transition portion of the plurality of inward transition portions to one outward transition portion of the plurality of outward transition portions is different from a number of turns in another range of the inner layer portion from another inward transition portion of the plurality of inward transition portions to another outward transition portion of the plurality of outward transition portions.
