There is provided an electronic control device in which a microcomputer and a power source IC are mounted, the electronic control device having high reliability and being capable of performing fixation diagnosis of a safety control signal of the power source IC before activation of the microcomputer. The electronic control device includes a microcomputer, and a power source IC that communicates with the microcomputer. The power source IC includes a monitoring circuit that monitors the microcomputer, a safety processing circuit that outputs a safety control signal when the monitoring circuit determines an occurrence of an abnormality in the microcomputer, and a diagnosis circuit that diagnoses whether or not the safety control signal has a fixation failure. The diagnosis circuit detects whether or not the fixation failure has occurred, based on states of the safety control signal before and after the safety control signal is activated after activation of a power source.
