Abstract
In a coil component, each time a first wire is wound around a central axis from a first wire end toward a second wire end and forms one turn, the number of turns of the first wire increases by one, and each time a second wire is wound around the central axis from a first wire end toward a second wire end and forms one turn, the number of turns of the second wire increases by one. A 35th turn of the second wire has a first crossing point where the 35th turn of the second wire on an outside of a 35th turn of the first wire crosses the 35th turn of the first wire, and a second crossing point where the 35th turn of the second wire on an outside of a 34th turn of the second wire crosses the 34th turn of the second wire.
Claims16
A coil component comprising:
- a winding core portion having a columnar shape;
- a first flange portion at a first end of the winding core portion in a direction along a central axis of the winding core portion;
- a second flange portion at a second end of the winding core portion opposite to the first end;
- a first outer electrode and a second outer electrode that are on the first flange portion;
- a third outer electrode and a fourth outer electrode that are on the second flange portion;
- a first wire wound around the winding core portion, the first wire having a first wire end and a second wire end, the first wire end of the first wire being connected to the first outer electrode, the second wire end of the first wire being connected to the third outer electrode;
- and
- a second wire wound around the winding core portion in the same direction as the first wire, the second wire having a first wire end and a second wire end, the first wire end of the second wire being connected to the second outer electrode, the second wire end of the second wire being connected to the fourth outer electrode, wherein
- each time the first wire is wound around the central axis in a direction from the first wire end toward the second wire end and forms one turn, a number of turns of the first wire increases by one, and
- each time the second wire is wound around the central axis in a direction from the first wire end toward the second wire end and forms one turn, a number of turns of the second wire increases by one,
- a j-th turn (j is an integer of 2 or more) of the second wire has
- a first crossing point where the j-th turn of the second wire on an outside of an i-th turn (i is an integer of 2 or more) of the first wire crosses the i-th turn of the first wire, and
- a second crossing point where the j-th turn of the second wire on an outside of a (j−1)-th turn of the second wire crosses the (j−1)-th turn of the second wire.
