摘要： A super-thin surface-mounting-type coil component, for mounting on a hybrid IC such as a DC-DC converter, is provided. Such a surface-mounting-type component comprises a core having a flat core portion in which the ratio of thickness to width (t/w) is not greater than 1/3, flange portions extending from both ends of the core portion in a longitudinal direction to be integrated with the core portion, two or four electrode layers spacedly positioned apart from each other and formed on peripheral portions, including side surfaces of the flange portions in at least a vertical direction, of the flange portions of the core. A winding is wound on the core portion of the core, having both ends obliquely led from the side surfaces of the flange portions and conductively fixed to the electrode layers of the side surfaces by thermo-compression bonding.
