Abstract: Disclosed herein is a coil component that includes conductor layers embedded in a base and terminal electrodes embedded in the base. Each of the terminal electrodes is exposed to a mounting surface of the base and a respective corner portion of the base. The conductor layers include connection patterns each connected to an associated one of the terminal electrodes. The first connection pattern is exposed to the third side surface without being exposed to the first side surface, the second connection pattern is exposed to the fourth side surface without being exposed to the first side surface, the third connection pattern is exposed to the third side surface without being exposed to the second side surface, and the fourth connection pattern is exposed to the fourth side surface without being exposed to the second side surface.

Abstract: Disclosed herein is a coil component that includes an element body having a mounting surface, a coil pattern embedded in the element body and having a coil axis extending perpendicular to the mounting surface, and a terminal electrode connected to the coil pattern and exposed to the mounting surface. The terminal electrode has a cutout part so as to avoid overlapping with the coil pattern in a plan view along the coil axis.

Abstract: Disclosed herein is a coil component that includes a first conductor layer having first and third planar spiral coils and second conductor layer having second planar spiral coil. The first planar spiral coil is positioned on an outer peripheral side of the third planar spiral coil. The first planar spiral coil has a pattern width larger than that of the third planar spiral coil. The second planar spiral coil is offset to the third planar spiral coil side in a plan view.
