Title:
ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2011/102088
Kind Code:
A1
Abstract:
Disclosed is an electronic component with which generation of defective products in the manufacturing process can be suppressed and also with which magnetic permeability and dielectric constant can be readily adjusted. A magnetic resin layer (3) is provided on the main face of a multilayer substrate (2) formed by baking, and therefore there is no need for the unified simultaneous baking of a laminated dielectric ceramic layer and magnetic ceramic layer that is conventionally performed. Also, there is no risk at all of generation of defects at the interface between the multilayer substrate (2) and the magnetic resin layer (3), said defects being caused by heat when baking, and consequently generation of defective products in the manufacturing process can be suppressed. The dielectric constant of the multilayer substrate (2) can be readily adjusted by forming the multilayer substrate (2) by laminating and baking a ceramic green sheet having the desired dielectric constant. Furthermore, the magnetic permeability of the magnetic resin layer (3) can be readily adjusted by mixing various types of magnetic material and resin material, and consequently the magnetic permeability and dielectric constant can be readily adjusted.
