持回路。A first switching element located between the output side of the stabilized power supply circuit and the voltage applied device detects the voltage on the output side of the power supply circuit, and when the voltage on the output side of the power supply circuit becomes below a predetermined value, Voltage detection means for placing the first switch element in a cut-off state, thereby cutting off the power supply current from the output side of the power supply circuit to the voltage applied device; and the output side of the power supply circuit that passes through the first switch element. a double-layer capacitor to which a charging current is supplied from through a high resistance, and a second switch element that becomes conductive when the voltage on the output side of the power supply circuit becomes lower than the voltage of the double-layer capacitor. 1. A power supply holding circuit characterized in that the discharge current is supplied from the double layer capacitor to the voltage applied device via the second switch element.
