A power-supply control device controls power-supply timings for supplying powers from an external power supply unit to a plurality of circuit elements having different power-supply timings. The circuit elements are grouped into a plurality of power-supply lines based on power-supply timings required by the circuit elements. The power-supply timings for supplying powers from the external power supply unit are controlled in an order in response to the power-supply timings required by the circuit elements for each of the power-supply lines.
