Abstract
The present disclosure provides an inductor, a manufacturing method therefor, a filter and an electronic device, belongs to the technical field of passive devices. The inductor according to the present disclosure includes a dielectric substrate and N coil structures disposed on the dielectric substrate; the N coil structures are nested and electrically connected in sequence, wherein N is an integer greater than or equal to 2. Any one of the coil structures includes a plurality of layers of sub-coils disposed on the dielectric substrate in sequence, and at least one interlayer insulating layer is disposed between sub-coils disposed adjacently, and adjacent layers of sub-coils are electrically connected through a first connection via penetrating the interlayer insulating layer between the adjacent layers of sub-coils.
