摘要： An inductor comprises a body and external electrodes arranged on an external surface of the body. The body includes a support member, a coil portion supported by the support member, and a sealing portion sealing the support member and the coil portion. The coil portion includes a plurality of coil patterns. A maximum thickness of each coil pattern in the plurality of coil patterns increases toward an outer portion of the body, and a line width of a lower surface in the coil patterns is wider than a line width of an upper surface.
