Inductor
An inductor device includes a first wire and a second wire. The first wire includes a first sub-wire and a second sub-wire. The first sub-wire is disposed in a first area. The second sub-wire is disposed in a second area, and the first sub-wire and the second sub-wire are located on different layers. The second wire includes a third sub-wire and a fourth sub-wire. The third sub-wire is disposed in the second area, and located below the second sub-wire. The fourth sub-wire is disposed in the first area, the third sub-wire and the fourth sub-wire are located on different layers, and the fourth sub-wire is located above the first sub-wire.
