Abstract
Official abstract text for this publication.
An electronic component includes a composite body composed of a composite material of a resin and a magnetic metal powder and a metal film disposed on an outer surface of the composite body. The magnetic metal powder contains Fe. The metal film mainly contains Cu, further contains Fe, and is in contact with the resin and the magnetic metal powder.
First claim
Opening claim text (preview).
What is claimed is: 1. An electronic component, comprising: a composite body composed of a composite material of a resin and a magnetic metal powder; and a metal film disposed on an outer surface of the composite body, the magnetic metal powder containing Fe, the metal film containing Cu in an amount of 95% by weight or greater, further containing Fe, and being in contact with the magnetic metal powder, wherein the metal film has an Fe content of from about 0.01% by weight to about 2.6% by weight with respect to Cu. 2. The electronic component according to claim 1 , further comprising: an inductor line disposed in the composite body and extending parallel to the outer surface; a substantially columnar line extending from the inductor line in a direction perpendicular to the outer surface, penetrating through the composite body, and being exposed at the outer surface; and a cover film covering the metal film, wherein the metal film is in contact with the substantially columnar line, and the metal film and the cover film are included in an external terminal. 3. The electronic component according to claim 1 , further comprising: an inductor line disposed in the composite body and extending parallel to the outer surface; a substantially columnar line extending from the inductor line in a direction perpendicular to the outer surface, penetrating through the composite body, and being exposed at the outer surface; and a cover film covering the metal film, wherein the metal film is in contact with the substantially columnar line, and the metal film and the cover film are included in an external terminal. 4. The electronic component according to claim 1 , wherein the metal film further contains Ni. 5. The electronic component according to claim 4 , further comprising: an inductor line disposed in the composite body and extending parallel to the outer surface; a substantially columnar line extending from the inductor line in a direction perpendicular to the outer surface, penetrating through the composite body, and being exposed at the outer surface; and a cover film covering the metal film, wherein the metal film is in contact with the substantially columnar line, and the metal film and the cover film are included in an external terminal. 6. A method for producing an electronic component according to claim 1 , the method comprising: forming a metal film on an outer surface of a composite body by electroless plating treatment, wherein the metal film is deposited on the magnetic metal powder containing Fe by an electroless plating treatment and is in contact with the resin.
