Provided are an inductor, which is vertically formed, and an electronic device having the inductor, and more particularly, an inductor capable of minimizing loss of a surface area and accomplishing high efficiency impedance by vertically forming the inductor in a plurality of insulating layers, and an electronic device having the same. The inductor includes a plurality of conductive lines disposed in the insulating layers; and vias vertically formed in the insulating layers to electrically connect the plurality of conductive lines. When a board or an electronic device including an inductor proposed by the present invention is manufactured, the inductor can occupy a minimum area in the electronic device or board while providing high inductance. In particular, the surface area of the electronic device or board occupied by the inductor can be remarkably decreased to reduce manufacturing costs.
