摘要： A production method of a multilayer inductor is provided as one capable of readily producing a multilayer inductor which can achieve satisfactory inductance and de bias characteristics together. In this production method of the multilayer inductor, there occurs interdiffusion of a Ni component in a magnetic layer and a Zn component in a nonmagnetic sheet to form an interdiffusion layer in a region of the nonmagnetic sheet inside a conductive pattern. This method allows the interdiffusion layer to be formed without need for complicated processing of the nonmagnetic sheet. Furthermore, there is no boundary region between the magnetic layer and the nonmagnetic sheet around it, which suppresses occurrence of cracking. In the multilayer inductor, the nonmagnetic layer is located between turns of a coiled conductor to suppress degradation of dc bias characteristics and a magnetic body penetrates in a region inside the coiled conductor to suppress reduction in inductance due to provision of the nonmagnetic layer between turns of the coiled conductor.

摘要： A laminated inductor, in which there is extremely little tendency for cracking to occur between adjacent conductor patterns in portions of a laminate in the lamination direction even when the conductor pattern thickness is large, as well as a method of manufacturing such a laminated inductor, are provided.A laminated inductor includes: a laminate; a pair of external electrodes arranged on the outer surfaces of the laminate respectively; and a coil, arranged within the laminate and formed by electrically connecting a plurality of strip-like conductor patterns. The conductor patterns have: a pair of broad faces, intersecting the lamination direction and mutually opposing; and peripheral side faces adjacent to the pair of broad faces and extending in the lamination direction. The peripheral side faces are concavo-convex faces, in which concave portions and convex portions are arranged in alternation in the lamination direction. The laminate enters into the concave portions of the peripheral side faces.
