    Abstract: An electronic device includes: a resin substrate that includes insulation resin on which wiring made of conductive material is provided; a heat-generation element that is a circuit element mounted on a first surface of the resin substrate, and is operated to generate heat; and a sealing resin that is provided on the first surface, and seals the heat-generation element. An opposite surface of the sealing resin opposite to a surface of the sealing resin in contact with the first surface is thermally connected to a heat radiation member and mounted on the heat radiation member. Each of the resin substrate and the sealing resin has a bend shape convex toward the opposite surface when each of surrounding temperatures is a normal temperature and has a linear expansion coefficient for maintaining a bend shape convex toward the opposite surface when each of the surrounding temperatures is a high temperature.
