Claim 0:
1. A coil component comprising:
a winding core having a peripheral surface around a central axis of the winding core, the peripheral surface including at least one plane extending in a direction along the central axis, the plane including a first end portion in a peripheral direction being a direction around the central axis and in which a first ridge extending in the direction along the central axis lies; and
a first wire and a second wire spirally wound with a plurality of turns around the central axis of the winding core in a same direction and forming a twisted section in which they are intertwisted in the plurality of turns, such that both the first wire and the second wire are in close contact with the first ridge in the twisted section at the plane in a single turn, wherein
the first ridge has a cut portion such that the winding core has two projecting portions formed at the first ridge, the projecting portions having a side that forms a point with a portion of the peripheral surface of the winding core parallel to the plane when viewed along the central axis, and the winding core has a pentagonal, hexagonal, or semispherical cross section when viewed along the central axis,
wherein when the winding core has a pentagonal or hexagonal cross section, the winding core includes a second ridge, a third ridge and a fourth ridge arranged at portions along the circumference of the winding core different from where the first ridge is located, the second ridge, third ridge and fourth ridge extending in the same direction as the first ridge, and
each of the second ridge, the third ridge and the fourth ridge has a cut portion such that the winding core has six projecting portions formed at the second ridge, the third ridge and the fourth ridge, the projecting portions having a side that forms a point with a portion of the peripheral surface of the winding core.
