Abstract
An inductor includes a body in which is disposed a coil connecting a plurality of coil patterns by a via. The via includes a first conductive layer and a second conductive layer disposed on the first conductive layer, and the via has an upper portion having a transverse cross-sectional area that is greater than a transverse cross-sectional area of a lower portion thereof. An interlayer contact area of coils may be increased, thereby improving electrical characteristics and connection reliability.
