Abstract
A vehicle power supply circuit includes; a plurality of switch circuits which are connected in parallel to each other and connected to a power supply at positive electrode side to be switched to an open or short circuit separately; a relay circuit including an excitation coil and a switch unit which is connected to the power supply at positive electrode side and is switched from an open circuit to a short circuit since a current flows from the power supply to the excitation coil; and a resistor disposed in parallel with the excitation coil and connected in series to the plurality of switch circuits.
