Abstract: Disclosed herein is a coil component that includes a drum core; a terminal fitting fixed respectively to the flange part of the drum core; and a wire wound around the winding core part of the drum core. The terminal fitting has a wire connecting part to which the wire is connected and a mounting part having springiness with respect to the drum core. The distance between the flange part and the mounting part is larger than the distance between the flange part and the wire connecting part.

Abstract: Disclosed herein is a coil component that includes a plate-like base member, a magnetic core mounted on the base member, a wire wound around the magnetic core such that an axis direction thereof is substantially parallel to the base member, and a terminal electrode fixed to the base member and connected to an end portion of the wire. The base member is made of a material having a permeability lower than that of the magnetic core.

Abstract: Disclosed herein is a common mode filter that includes first and second wires wound in the same direction around the winding core part. The first and second wires have first to third layer winding portions, a first crossing portion positioned between the first and third layer winding portions, and a second crossing portion positioned between the second and third layer winding portions. The vertical positions of the first and second wires are reversed at least partially between the first and third layer winding portions, and the vertical positions of the first and second wires are reversed at least partially between the second and third layer winding portions.

Abstract: Disclosed herein is a coil component that includes a winding core part and a wire wound around the winding core part. An i-th turn (i is an integer equal to or larger than 1) to a j-th turn (j is an integer equal to or larger than (i+2)) of the wire are wound in this order around the winding core part in an aligned state. A (j-th+1) turn of the wire is wound around a valley line formed by the i-th turn and a (i-th+1) turn. A (j-th+2) turn of the wire is wound adjacent to the j-th turn around the winding core part.
