Abstract
A coil component includes a substrate, a planar spiral conductor formed on a top surface of the substrate, a lead conductor connected to an outer peripheral end of the planar spiral conductor, a dummy lead conductor formed on the top surface of the substrate between an outermost turn of the planar spiral conductor and an end of the substrate and free from an electrical connection with another conductor within the same plane, external electrodes and arranged in parallel with the top surface of the substrate, and a bump electrode formed on a surface of the lead conductor and connects the lead conductor with the external electrode. The external terminals have a larger area than the bump electrodes for securing a bonding strength.
