PROBLEM TO BE SOLVED: To suppress the release of electric charges from a capacitor when a DC-DC converter is not operating in intermittent operation thereof. SOLUTION: A DC-DC converter circuit (230) includes a boosting circuit (231) having at least part of a DC-DC converter (233); a control signal circuit (232) that controls the boosting circuit; and a power supply means (C4) being electrically connected to both of the boosting circuit and the control signal circuit and supplying at least the control signal circuit with electric power. The DC-DC converter includes a plurality of capacitors (C1-C3) and switching means (SW1a-SW5a) enabling each of the plurality of capacitors to be electrically independent, and the control signal circuit transmits a signal to the switching units when the DC-DC converter is not operating in intermittent operation thereof, the signal indicating each of the plurality of capacitors being made to be electrically independent.
