Abstract:
1. An electronic device comprising: a substrate that includes a first surface and a second surface opposite to the first surface; an electronic element mounted on a first portion of the first surface of the substrate; a metal plate bonded to the second surface of the substrate so as to expose a second portion of the second surface of the substrate opposite to the electronic element; and a resin mold that seals the first surface of the substrate and seals the second surface of the substrate so as to expose the metal plate, wherein the resin mold sandwiches the first portion of the first surface and the second portion of the second surface of the substrate, wherein the resin mold seals entire area of the second portion of the second surface of the substrate, wherein the resin mold on the second portion of the second surface is the same as the resin mold on the first surface, wherein the resin mold covers an outer periphery of the metal plate, and wherein a thickness of the resin mold on the second portion of the second surface of the substrate is larger than a thickness of the metal plate on the second surface of the substrate.
