A coil device includes a first conductor, a second conductor, and a core. The second conductor is disposed inside the first conductor and at least partly extending along the first conductor. The core internally arranges the first conductor and the second conductor. An insulating layer is formed at least between the first conductor and the second conductor.

Coil device

A coil device includes a first core, a second core, and a conductor. The first core includes a first leg. The second core is disposed with a gap between the first leg and the second core. The conductor is at least partly disposed between the first core and the second core. A notch is formed on the conductor at a position corresponding to the gap.

A coil device capable of reducing magnetic coupling between conductors while ensuring good inductance characteristics is provided. A coil deviceincludes a first core, a second corecombined with the first core, and a first conductorand a second conductorarranged adjacent to each other between the first coreand the second core. At least one of the first coreand the second coreincludes a center leg portion(or a center leg portion) and a pair of outer leg portions(or outer leg portions) arranged on both sides of the center leg portion(or center leg portion), and a magnetic body is arranged between the first conductorand the second conductor

Coil component

A coil device includes a core, a coil, a mounting part, and a bottom raising part. The coil is at least partly disposed close to the core. The mounting part is mounted on an installation surface. The bottom raising part is connected with the coil and extends to the mounting part so as to form a gap having a predetermined height between the mounting part and a bottom surface of the core.

An inductor element includes a core including a first core portion and a second core portion that are disposed to face each other in a first direction; and a conductor including a first mounting portion and a second mounting portion that are exposed from the core at a predetermined interval therebetween on one side of a second direction orthogonal to the first direction, and a connecting portion which connects the first mounting portion and the second mounting portion and of which at least a part is interposed between the first core portion and the second core portion. The first mounting portion and the second mounting portion are disposed to overlap both of the first core portion and the second core portion as seen from the second direction.

Inductor element

An inductor element includes a first conductive portion, a second conductive portion, and a magnetic core. The first conductive portion includes a first round-about portion, a first mount portion, and a second mount portion. The second conductive portion includes a second round-about portion, a third mount portion, and a fourth mount portion. The magnetic core houses at least a part of the first and second conductive portions so that each mount surface of the first to fourth mount portions is exposed from one side of the magnetic core. The first and second conductive portions are arranged so that the first and second directions are substantially parallel and opposite to each other. The first and third mount portions are at least partially overlapped with each other in a third direction perpendicular to the first and second directions.

A coil device includes a pair of first core and second core, a third core, and a pair of first coil and second coil. The third core is disposed next to the first core or the second core. The pair of first coil and second coil is each disposed between any two of the first core, the second core, and the third core next to each other. Plate surfaces of the first coil and the second coil are opposed to each other. Each of the first coil and the second coil is partly exposed in a lateral direction of the first core, the second core, or the third core.

A coil device includes a core and a plurality of coils arranged in the core. A distance of a second gap formed by portions of the core located inside at least one of the coils is larger than that of a first gap formed by other portions of the core located between the coils next to each other.
