摘要： The present disclosure provides an inductive element capable of lowering a Q-value. An inductive element includes a first cover and a second cover covering an annular core, and a first winding and a second winding wound around a region of the core, the first cover and the second cover. The first cover covers a part of an inner circumferential surface of the core, a part of an outer circumferential surface and an end surface on one end side in an axial direction. The second cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface an end surface on the other end side in the axial direction.

摘要： A compound line filter includes a bobbin, two coils and a magnetic core. The coils are wound on the bobbin in a state of being separated from each other in an axial direction. The magnetic core includes a closed magnetic path part and a secondary magnetic path part. The bobbin is attached to the closed magnetic path part. The secondary magnetic path part extends from the closed magnetic path part in a direction intersecting with the axial direction and is positioned between the coils in the axial direction. The bobbin includes at least one gear, and the gear is positioned between the coils in the axial direction.
