A spiral inductor device is provided. The spiral inductor device comprises an insulating layer disposed on a substrate. A spiral conductive trace with multiple turns is disposed on the insulating layer, wherein the outermost turn and the innermost turn of the spiral conductive trace have a first end and a second end, respectively, and one of the first and second ends is connected to ground. A non-continuous spiral conductive trace with a single turn is disposed on the insulating layer, parallel and adjacent to the turn that belongs to the spiral conductive trace and is extended from the end of the spiral conductive trace without being connected to ground, wherein the non-continuous spiral conductive trace is connected to the ground.
