Abstract
An electronic control device includes a plurality of circuit boards that transmit signals to each other and a power supply connector for direct-current power. A ground line connected to a ground terminal of the power supply connector is connected to a ground of one of the plurality of circuit boards by way of a ground of another one of the plurality of circuit boards. In this way, the electronic control device including the plurality of circuit boards needs fewer noise reduction components while enabling easier routing of ground lines.
