Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
