Zusammenfassung:The invention provides a coil component and a circuit board provided with the coil component, and aims to sufficiently ensure the area of a terminal electrode and reduce the parasitic capacitance of a coil pattern in the coil component of which the mounting surface is perpendicular to the coil axis direction. A coil component (1) is provided with: an element body (2) having a mounting surface (S1); coil patterns (C1-C4) embedded in the element body (2) and having a coil axis direction perpendicular to the mounting surface (S1); and terminal electrodes (E1-E4) connected to the coil patterns (C1-C4) and exposed to the mounting surface (S1). The terminal electrodes (E1-E4) are provided with cutout portions (A) so as not to overlap the coil patterns (C1-C4) in a plan view as viewed from the coil axis direction. As a result, the parasitic capacitance of the coil patterns (C1-C4) can be reduced while ensuring the exposed area of the terminal electrodes (E1-E4) on the mounting surface (S1). 本发明提供线圈零件和具备该线圈零件的电路基板,其目
