The invention provides an electronic device, and a method for controlling power to a control unit of the electronic device. The electronic device includes power-on control means (611) configured to instruct first voltage generation means (601) to generate a first voltage in accordance with a power-on instruction, determine whether or not the first voltage generated by the first voltage generation means (601) has become a predetermined voltage or higher, and instruct second voltage generation means (602) to generate a second voltage when the power-on control means (611) determines that the first voltage has become the predetermined voltage or higher; and power-off control means (631) configured to instruct the second voltage generation means (602) to stop generation of the second voltage in accordance with a power-off instruction, and instruct the first voltage generation means (601) to stop generation of the first voltage after a predetermined time period has elapsed from the power-off instruction.
