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.
