Abstract
A coil component 1 includes a substrate 2, a planar spiral conductor 10a formed on a top surface 2t of the substrate 2, a lead conductor 11a connected to an outer peripheral end of the planar spiral conductor 10a, a dummy lead conductor 15a formed on the top surface of the substrate 2 and between an outermost turn of the planar spiral conductor 10a and an end 2X2 of the substrate 2 and free from an electrical connection with another conductor within the same plane, external electrodes 26a and 26b arranged in parallel with the top surface of the substrate 2, and a bump electrode 25a formed on a surface of the lead conductor 11a and connects the lead conductor 11a with the external electrode 26a. The external terminals 26a and 26b have a larger area than the bump electrodes 15a and 15b for securing a bonding strength.
