Inductive element and LC filter

An inductive element comprising:

• an annular core;
• a first cover and a second cover covering the core;
• and
• a first winding and a second winding wound around a region of the core and the first and second covers, wherein
• when a direction in which an axis which is surrounded by the annular core extends is defined as an axial direction,
• the core includes an inner circumferential surface, an outer circumferential surface, an end surface on one end side in the axial direction, and an end surface on the other end side,
• the first cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface thereof, and the end surface on the one end side of the core, and includes an inner end surface extending over the inner circumferential surface of the core and an outer end surface extending over the outer circumferential surface thereof,
• the second cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface thereof, and the end surface on the other end side thereof, and includes an inner end surface extending over the inner circumferential surface of the core and an outer end surface extending over the outer circumferential surface thereof,
• the inner end surfaces of the first and second covers are spaced apart from each other, and
• the outer end surfaces of the first and second covers are spaced apart from each other,
• wherein
• the inner end surfaces of the first and second covers are spaced apart from each other by a predetermined interval over their entire areas, and
• the outer end surfaces of the first and second covers are spaced apart from each other by a predetermined interval over their entire areas,
• wherein the interval between the inner end surfaces of the first and second covers is larger than the interval between the outer end surfaces of the first and second covers.
