Electronic component packaging structure and method for producing the same
An electronic component packaging structure, includes: circuit boards each having a wiring at least on a surface thereof; and an electronic component package secured between the circuit boards. The electronic component package includes at least one electronic component embedded within an electrical insulating encapsulation resin molded member made of an inorganic filler and a resin, the at least one electronic component being selected from an active component and a passive component, protruding electrodes are arranged on both faces of the electrical insulating encapsulation resin molded member, and the electronic component is connected electrically with at least a part of the protruding electrodes. This configuration allows circuit boards to be connected with each other and a high-density and high-performance structure.
