Abstract
To fill a conductive material in an opening portion formed in a base of an electronic component, a groove is formed to surround an opening in an upper conductor, and the upper conductor is divided into a first conductive portion and a second conductive portion surrounding the first conductive portion. A mask is formed such that a conductor to be filled in the opening portion may not contact the second conductive portion. Metal plate is grown from the side of a lower conductor in the opening portion by using the lower conductor as electrode to fill the opening portion with metal plate. The metal plate filled in the opening portion and the upper conductor are joined by plating by using the upper conductor or the lower conductor as electrode.
