发明名称 METHOD FOR MANUFACTURING STACKED COIL COMPONENT
摘要 <P>PROBLEM TO BE SOLVED: To effectively manufacture a stacked coil component which excels in planarity and smoothness of surface, high in reliability of surface adsorption by an automatic mounting machine, and which is less apt to have a magnetic layer peel off, without causing reduction in the yield due to defective appearance. Ž<P>SOLUTION: When the stacked coil component equipped with a magnetic stack, having a lamination direction center region 11 containing a stacked coil 20 and an outer region constituted of a magnetic layer 1b laminated on the outer side of the lamination direction is manufactured, a green sheet (green sheet for placing a level difference resolving material C) with a level difference resolving material 21 for resolving the level difference formed between a region where a conductor pattern 2a is placed and its surrounding region is used as at least a portion of a green sheet for the outer layer region, in a step where a green sheet for lamination direction center region, which includes a green sheet with a conductor pattern placed for an inside conductor, and a green sheet for outer layer region without conductor pattern placed are laminated and crimped onto each other to form a magnetic stack 10a which is yet to be baked.
