Abstract
A multilayer coil component includes internal conductors made of silver (Ag) having metal films provided on surfaces thereof to suppress migration of Ag contained in the internal conductors and/or relieve internal stress between magnetic ceramic layers and internal conductor layers without forming gaps at interfaces between the internal conductors including the metal films and a magnetic ceramic surrounding the internal conductors and the interfaces between the internal conductors and the magnetic ceramic. In a manufacturing method for forming a multilayer coil, an acidic solution containing a metal is allowed to penetrate a magnetic ceramic through side surfaces thereof and side gap sections that are regions between side portions of internal conductors and the side surfaces to reach the interfaces between the internal conductors and a surrounding magnetic ceramic, whereby the metal is deposited on surfaces of the internal conductors.
