A current flow control device includes a plurality of semiconductor switches disposed between a power source and a load and that are connected in parallel with each other, and the current flow control device being configured to control the flow of current between the power source and the load by turning on and off the semiconductor switches. The plurality of semiconductor switches include a first and a second semiconductor switch. The current flow control device includes a driving circuit configured to apply, to the first semiconductor switch, a voltage that is higher than a voltage output from the power source, to turn on the first semiconductor switch, a switch control unit configured to turn on the second semiconductor switch, and a resistor that is connected in series with a terminal on the power source side of the second semiconductor switch, the resistor lowering a voltage applied to the terminal.
