A vehicular control device includes a control unit that controls an electrical component, a wake-up circuit that wakes up the control unit on the basis of a wake-up signal from a switch for operating the electrical component, and a wake-up stop circuit that interrupts the wake-up signal supplied from the switch to the wake-up circuit after a predetermined length of time has elapsed from a wake-up instruction. The vehicular control device is put to sleep by forcibly interrupting the wake-up signal in the wake-up stop circuit, regardless of the state of the switch after the predetermined length of time has elapsed from the wake-up instruction, and thus it is possible to prevent a wake-up state from being maintained even in a case where the switch is fixed in an on-state.
