Abstract
A power supply control device for a vehicle controls power supply to a first load. A first controller is formed on a first substrate and controls power supply to the first load. A second controller is formed on a second substrate that is different from the first substrate, and instructs the first controller to perform an operation regarding power supply. The first controller and the second controller include a first switch and a circuit switch, respectively. The first switch and the circuit switch are provided on a current path of a current flowing via the first load. The second controller provides an instruction to switch the first switch on or off.
