This coil component comprises a core having a through-hole, and a coil part that passes through the through-hole and is wound onto the core. The coil part includes a first conductor part and a second conductor part. The first conductor part includes a first section that penetrates from a first side to a second side in a first direction that is the penetration direction of the through-hole, a second section that extends to the outer peripheral side from the inner peripheral side of the core, and a third section that extends toward the first side passing along the outer peripheral side of the core. The second conductor part includes a fourth section that penetrates from the second side to the first side in the first direction, a fifth section that extends to the outer peripheral side from the inner peripheral side of the core, and a sixth section that extends toward the second side passing along the outer peripheral side of the core. The third section and the sixth section each have an overlapping section that overlaps with the other in the first direction, and are connected in the overlapping sections.
