PROBLEM TO BE SOLVED: To provide a small coil substrate having a low resistance value, a coil component, and a manufacturing method thereof. A coil substrate 100 and a coil component 1 manufactured by the method of the present invention are made by plating and growing a conductor pattern (planar coil 34), so that the distance (G) between conductors is reduced. The portion 34K in the vicinity of the top surface of the conductor, which has become higher with the plating growth of the conductor, is flattened by polishing or cutting, so that the size is reduced. That is, the coil base material and the coil component are small and have a low resistance value. [Selection] FIG. |
