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.

Abstract: A coil device includes a main core and a sub core. The main core includes a middle leg for winding a coil body and an outer leg connected with the middle leg via a base portion. The sub core is disposed to face the base portion across the middle leg. A gap between the middle leg and the sub core is wider than that between the outer leg and the sub core.

Abstract: A core device includes: a core having a mounting surface; a first conductor including a first body portion extending along the mounting surface inside the core; and a second conductor including a second body portion that extends along the mounting surface inside the core and faces the first body portion. The first body portion has a first side surface having a first thickness in a direction perpendicular to the mounting surface and a first main surface having a first width in a direction parallel to the mounting surface. The second body portion has a second side surface having a second thickness in the direction perpendicular to the mounting surface and a second main surface having a second width in the direction parallel to the mounting surface. The second width is narrower than the first width when the first body portion and the second body portion face each other.
