Zusammenfassung:Provided is a thin-film power inductor. The thin-film power inductor includes a magnet, a first port electrode, and a second port electrode. The magnet includes at least one first sub-structure. A first sub-structure includes a first upper functional layer, a first upper coil, a first upper adhesive layer, a first insulating layer, a first lower adhesive layer, a first lower coil, and a first lower functional layer that are stacked in sequence. A first end of the first upper coil and a first end of the first lower coil are exposed to a same surface of the magnet and are both electrically connected to the first port electrode. A second end of the first upper coil and a second end of the first lower coil are exposed to a same surface of the magnet and are both electrically connected to the second port electrode.
