Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power supply control system, a power supply control device, and a power supply control method which enable power supply/power cutoff to separately be switched to each of a plurality of electronic devices connected to a network.SOLUTION: When the power supply control device 3 outputs a control signal to a power switch device 2 to cut off power supply to ECUs 6a, 6b, etc., the power supply control device 3 carries out periodical data transmission in place of the ECUs 6a and 6b cut off from power supply. This allows other ECUs 5a and 5b not cut off from power supply to receive data from the power supply control device 3 that is equivalent to data periodically transmitted by the ECUs 6a and 6b cut off from power supply. Moreover, the power supply control device 3 stores therein a transmission period, a transmission ID, and latest reception information for each of the ECUs 6a and 6b to be controlled, and transmits data containing the latest reception information in place of them.
