Abstract:
1. A vehicle-mounted electronic apparatus comprising: a case, in which part of a bottom surface or a side surface has an opening; a connector that sticks out from the opening of the case and that can be connected to an external device that inputs and outputs an electrical signal and an external power supply that supplies power; a circuit substrate that is provided inside the case, on which the connector is mounted, and that, by electrically connecting with the connector, performs signal processing using the electrical signal received as input from the external device and the power supplied from the external power supply; a metallic wiring board that comprises a plurality of metallic wires, and that is embedded in a bottom portion surface of the case and electrically connects with the circuit substrate; and a heat-generating electronic component that has its bottom surface connected on part of metallic wires in the metallic wiring board, wherein: the connector includes a connector terminal formed of a metal for electrical connection; and a thickness of a metallic wire in the metallic wiring board that connects with the bottom surface of the heat-generating electronic component is thicker than thickness of the connector terminal.
