Electronic component and method for manufacturing the same

Abstract

An electronic component is provided with a first conductor, an insulator for covering a surface of the first conductor, a via hole penetrating the insulator, and a second conductor located on a surface of the insulator and electrically connected to the first conductor through the via hole, and includes a shielding film having conductivity, being interposed between the first conductor and the second conductor, and covering an interface between the first conductor and the insulator in the via hole by extending continuously at least from the surface of the first conductor constituting a bottom surface of the via hole to an inner wall surface of the via hole.
