Abstract
A core substrate-less electronic device is fabricated by using an electronic device substrate. The electronic device substratea metal core substrate, and an external connection wiring layerprovided on the metal core substrate, and an electronic parts-mounting layerprovided on the external connection wiring layer. The external connection wiring layerhas a first plating filmas an external connection terminal, and a PSR filmas an electrical insulating material. The electronic parts-mounting layerhas a conductive filmas an internal conductor pattern and a PSR filmas an electrical insulating material. A surface of the conductive filmis in a same plane as a surface of the PSR film
