An inductor comprises an insulating substrate; a first internal coil portion disposed on one surface of the insulating substrate and a second internal coil portion disposed on the other surface of the insulating substrate opposed thereto; a via electrode penetrating through the insulating substrate to connect the first internal coil portion to the second internal coil portion; and a first via pad disposed on one surface of the insulating substrate and a second via pad disposed on the other surface of the insulating substrate, to cover the via electrode. Respective cross-sectional areas of an upper portion and a lower portion of the via electrode, in contact with the first via pad and the second via pad, are greater than a cross-sectional area of a central portion thereof. In addition, a method of manufacturing the inductor is provided.
