Abstract

An inductor includes first and second external electrodes spaced apart from each other, a substrate disposed between the first and second external electrodes and having a first surface and a second surface opposing each other, and a conductive structure electrically connected to the first and second external electrodes. The conductive structure includes a first conductive pattern disposed on the first surface of the substrate, a second conductive pattern disposed on the second surface of the substrate, and at least one reinforcing portion. The first conductive pattern has a first side facing the first external electrode, the second conductive pattern has a second side facing the second external electrode, and the at least one reinforcing portion is electrically connected to at least one of the first and second sides and is interposed between the substrate and at least one of the first and second external electrodes.
