Abstract: A filter includes at least two coil assemblies, a plurality of wiring harnesses, at least one dielectric mechanical part, and at least two wiring layers disposed in a stacked manner, where each coil assembly includes a plurality of wires, and one or more wires belonging to different coil assemblies are disposed in each wiring layer; each wiring harness is coupled to two different wires of a same coil assembly, to sequentially couple the wires of each coil assembly together; and each dielectric mechanical part is located between two adjacent wiring layers, wiring layers are stacked together under effect of the dielectric mechanical part, and a volume of each dielectric mechanical part is less than a volume of interlayer space between two wiring layers that are in contact with each dielectric mechanical part.
