PROBLEM TO BE SOLVED: To provide a vehicular power supply control device capable of eliminating the power supply interruption-inability state attributable to the functional deficiency. SOLUTION: The vehicular power supply control device 10 comprises an interruption request detection means 3 for detecting the interruption request of a vehicular power supply, an electronic control means 2 which starts the finishing control when detecting the interruption request and outputs the power supply keeping request before the finishing control is completed, and a master electronic control means 1 which keeps the power supply to the electronic control means 2 while outputting the power supply keeping request and interrupts the power supply to the electronic control means 2 when not outputting the power supply keeping request. The master electronic control means 1 has an inquiry means 1b for making an inquiry for determining whether or not the power supply keeping request is correct to the electronic control means 2 after the elapse of a predetermined time from the detection of the interruption request.
