    Abstract: Disclosed herein is a common mode filter that comprises a drum core including a winding core portion and a pair of flange portions provided at both ends of the winding core portion, and first and second wires wound around the winding core portion so as to form a pair-wire for each turn. The first and second wires includes one or a plurality of sparsely-wound portions in which the first and second wires are wound with adjacent pair-wires spaced from each other, and one or a plurality of closely-wound portions in which the first and second wires are wound with adjacent pair-wires in close contact with each other.

    Abstract: A device includes a core having a first end and a second end, and first and second wires wound around the core, where the core has first, second, and third sections, the second section being arranged between the first and third sections. Each of the first and second wires includes an ith turn located on the first section, a jth turn located on the second section, and a kth turn located on the third section. The ith turn of the first wire is closer to the first end than the ith turn of the second wire, the jth turn of the first wire is closer to the second end than the jth turn of the second wire, and the kth turn of the first wire is closer to the first end than the kth turn of the second wire.

    CPC classification number: H01F27/29

    Abstract: An inductor 1 includes a coil 2 made of a flat wire, a terminal 4a including a wire connecting portion 42a connected to a lead portion 3a of the coil 2, a terminal 4b including a wire connecting portion 42b connected to a lead portion 3b of the coil 2, and a core 8 that covers the coil 2 together with the wire connecting portion 42a and the wire connecting portion 42b. The wire connecting portion 42a is positioned outside the lead portion 3a that is led out in a front-rear direction of the core 8, along a left-right direction of the core 8. The wire connecting portion 42b is positioned outside the lead portion 3b that is led out in the front-rear direction of the core 8, along the left-right direction of the core 8.
