A power supply control device includes an electrical power generating unit that generates electrical power and supplies the generated electrical power to an electronic device having a nonvolatile memory and a control unit; a switching unit that monitors a voltage of electrical power supplied to the electronic device, and switches such that, when the voltage is less than a predetermined threshold value, the electrical power is supplied to the control unit and is not supplied to the nonvolatile memory; and a capacitor that maintains, when the electrical power is switched to be supplied to the control unit, a voltage applied to the nonvolatile memory for a period of time during which writing of data to the nonvolatile memory can be completed.
