An information device for on-vehicle use, includes: a CPU which is capable of normal operation and of standby operation which achieves low power consumption; a first power supply for use during the normal operation of the CPU; a second power supply for use during the standby operation of the CPU; and a power control device which performs ON-OFF control of the first power supply and the second power supply. And the CPU outputs a first signal to the power control device when the CPU transits from the normal operation to the standby operation; the power control device outputs a second signal to the second power supply which turns the second power supply ON when the first signal has been inputted from the CPU, and outputs a third signal to the first power supply which turns the first power supply OFF after a predetermined time period has elapsed after the output of the second signal; the CPU outputs a fourth signal to the power control device when the CPU transits from the standby operation to the normal operation; and the power control device outputs a fifth signal to the first power supply which turns the first power supply ON when the fourth signal has been inputted from the CPU, and outputs a sixth signal to the second power supply which turns the second power supply OFF after a predetermined time period has elapsed after the output of the fifth signal.
