A power supply control circuit includes a control circuit that controls an output transistor to be rendered conductive by forming a second electrical path between a second power supply line and a control terminal of the output transistor when a power supply voltage is applied in a reverse direction between first and second power supply lines, and that controls a second electrical path to be electrically disconnected when the power supply voltage is applied in a forward direction between the first and second power supply lines.
