An inductor structure includes a winding turn layer, a shielding layer, and a number of vias. The winding turn layer disposed above a substrate is formed by a number of turns connected in series and t has a first end and a second end. The first end is grounded. The shielding layer disposed between the winding turn layer and the substrate has a third end and a fourth end. At least two turns starting from the first end of the winding turn layer are projected onto the shielding layer. The vias are disposed between the winding turn layer and the shielding layer to at least electrically connect the third end and the fourth end of the shielding layer to a first turn of the winding turn layer. The first turn starts from the first end, and the winding turn layer and the shielding layer are electrically coupled in parallel.
