Abstract

Abstract An electronic device mounting wiring board having an electronic device mounted on the surface of a wiring substrate or inside thereof is provided. The wiring substrate includes an insulation substrate made by laminating a plurality of insulation layers that include a thermosetting resin, a wiring circuit layer formed on the surface of and inside of the insulation substrate and via hole conductors. A resin layer having a glass transition temperature lower than the curing temperature of the thermosetting resin is formed between at least one of top and bottom surfaces of the electrical device and the insulation layer.
