1. An inductor comprising:
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,
wherein the conductive structure comprises 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,
wherein the first conductive pattern has a first side facing the first external electrode,
wherein the second conductive pattern has a second side facing the second external electrode,
wherein the at least one reinforcing portion is 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,
wherein the at least one reinforcing portion comprises a first reinforcing portion extending from at least a portion of the first side of the first conductive pattern in a first direction,
wherein the first direction is a direction from the first surface of the substrate toward the second surface of the substrate,
wherein the conductive structure further comprises a first expansion part spaced apart from the second conductive pattern,
wherein the first reinforcing portion is disposed between the first expansion part and the first side of the first conductive pattern, and
wherein the first side, the first reinforcing portion, and the first expansion part are in electrical contact with the first external electrode.
