PROBLEM TO BE SOLVED: To solve the problem of a conventional system of detecting the existence of a leaked current through the leaked current detecting circuit in an electronic apparatus, such as that it can not prevent the wasteful consumption of a battery. SOLUTION: This electronic apparatus is equipped with the first power supply means which has specified impedance R1 and performs the power supply, according to the signal of a control circuit 3 having received the directions of operation start of an apparatus, and the second power supply means (a path via a MOS switch 10) which has lower impedance than this first power supply means and performs power supply, according to the power supplied from the first power supply means going up to a specified level, and also this stops the power supply from the first power supply means when the power supplied from the first power supply means does not reach the above specified level though the power supply from the first power supply means is performed.
