Abstract:
1. A method of manufacturing an electronic-parts-packaging structure, comprising the steps of: forming a first resin film uncured on a wiring substrate including a wiring pattern, before a plurality of electronic parts are mounted; burying the electronic parts having a connection terminal on an element formation surface in the first resin film uncured in a state where the connection terminal is directed upward, by pushing the electronic parts from a surface of the first resin film uncured to inside the first resin film uncured, and a back surface of the first resin film uncured, and the back surface side of the electronic parts being electrically isolated from the wiring substrate; forming a second resin film for covering the electronic parts; obtaining an insulation film by curing the first and second resin films by heat treatment; forming a via hole in a predetermined portion of the insulation film on the wiring pattern and the connection terminal; and forming an upper wiring pattern connected to the wiring pattern and the connection terminal through the via hole, on the insulation film.
