Abstract
A thin film type inductor includes a body and external electrodes disposed on an external surface of the body. The body includes a support member and an internal coil supported by the support member, the internal coil includes an upper coil disposed on one surface of the support member and a lower coil disposed on the other surface thereof, and the upper and lower coils are connected to each other by a via electrode. Heights of a plurality of coil patterns arranged along a first virtual line are substantially equal to each other, and heights of a plurality of coil patterns arranged along a second virtual line increase toward the external surface of the body, where the first virtual line radiates from a center of a core of the body toward the via electrode and the second virtual line radiates in the opposite direction.
