PROBLEM TO BE SOLVED: To provide a power source control system and an electronic device capable of starting a plurality of electronic devices mounted to a vehicle according to a need while restraining the number of power lines in a vehicle from increasing and restraining costs from increasing. SOLUTION: A plurality of ECUs 3Aa, 3Ab... mounted to a vehicle are classified into a plurality of groups, and the ECUs 3Aa, 3Ab... in each group are connected to each other with common control signal lines 6a-6c. A power source control device 2 outputs control signals to the respective control signal lines 6a-6c. In Each of ECUs 3Aa, 3Ab..., a power source IC switches supply/non-supply of power to each part according to a signal level of the control signals from the power source control device 2. A common power line 5 supplies power to the ECU 3Aa, 3Ab from a battery 1. COPYRIGHT: (C)2011,JPO&INPIT
