Document Type and Number:
Japanese Patent JP6502627
Kind Code:
B2
Abstract:
A method of manufacturing a coil component having terminal electrodes with high mounting strength, includes: embedding an air-core coil in complex magnetic material being a mixture of resin and metal magnetic grains, molding the magnetic material so that both ends of the coil are exposed on its surface, curing the resin in the molding, thereby obtaining a magnetic body in which the coil is embedded, polishing and etching a surface where the ends of the coil are exposed, sputtering metal material onto an etched surface of the magnetic body, thereby forming an underlying layer across a surface of the magnetic body and ends of the coil, and then forming a cover layer that covers an outer side of the underlying layer, thereby forming terminal electrodes constituted by the underlying layer and cover layer.
