<P>PROBLEM TO BE SOLVED: To prevent the outmost periphery of a flat surface spiral conductor from exposing on a side surface of a coil component. <P>SOLUTION: A coil component 1 includes: a substrate 2; a flat surface spiral conductor 10a formed on a front surface 2t of the substrate 2 by electrolytic plating; and a flat surface conductor 15a which is formed between the outermost periphery of the flat surface spiral conductor 10a and an end part of the substrate 2, from among the front surface 2t of the substrate 2, and is not connected with other conductors on at least the same plane. The flat surface conductor 15a inhibits a plating layer of the outermost periphery from growing in the lateral direction. Thus, the structure prevents the outmost periphery of the flat surface spiral conductor from exposing on a side surface of the coil component. <P>COPYRIGHT: (C)2013,JPO&INPIT |
