An inductor includes a coil substrate, an encapsulation material containing a magnetic material and selectively covering the coil substrate, and first and second external electrodes formed on the exterior of the encapsulation material. The coil substrate includes a laminate of stacked structures each including a conductive track and first and second connection parts on opposite sides of the conductive track in a single wiring layer. The conductive tracks are connected in series to form a helical coil. The first connection parts are connected by a first via to form a first electrode terminal connected to a first end of the helical coil. The second connection parts are connected by a second via to form a second electrode terminal connected to a second end of the helical coil. The first and second external electrodes are connected to the first and second electrode terminals, respectively.
