1. A coil component comprising:
a drum-shaped core including a core part, a first flange part, and a second flange part, the core part having a circumferential surface including a first surface and a second surface parallel to each other; and
a coil including two wires wound around the core part in a same direction,
wherein
the coil has at least one first twisted wire part having the two wires twisted together on the first surface, and at least one second twisted wire part having the two wires twisted together on the second surface,
for at least one turn of the two wires wound around the core part, an entirety of the at least one first twisted wire part on the first surface and an entirety of the at least one second twisted wire part on the second surface are identical in shape,
the two wires are connected to mounting surfaces of the first flange part and the second flange part at positions spaced from a center of the mounting surfaces of each of the first flange part and the second flange part, and
for at least one turn of the two wires wound around the core part, the two wires overlap each other only a single time on two adjacent surfaces of the core part, each overlap being in a direction perpendicular to a respective one of the surfaces of the core part.
