This invention discloses an integrated inductor structure, including a first metal trace, a second metal trace, and a connecting metal trace. Tow terminals of the connecting metal trace are respectively connected to the first metal trace and the second metal trace through at least a connecting structure. The connected first metal trace, the connecting metal trace and the second metal trace together form an inductor structure. The connecting structure is connected to a connecting area of the first metal trace. The connecting area of the first metal trace has a first width. A smallest width of the first metal trace is a second width. The second width is smaller than the first width.
