To provide the automatic faucet that can suppress power consumption of a battery.SOLUTION: The automatic faucet 1 comprises the battery 81, a boosting circuit 82 that boosts and outputs an output voltage from the battery 81, and a capacitor 83 that is charged based on the output voltage from the boosting circuit 82. Further, the automatic faucet 1 comprises a raw water sensor 60A driven based on electric power supplied from the capacitor 83, a water purification sensor 60B, a raw water on-off valve 40, and a water purification on-off valve 42, and a control circuit 71 that operates based on the electric power supplied from the battery 81 and controls driving of these loads. The control circuit 71 switches between on control in which a boosting circuit 82 performs boost operation and off control in which the boosting circuit 82 does not perform the boost operation.SELECTED DRAWING: Figure 2 【課題】バッテリの消費電力を抑制し得る自動水栓を提供する。【解決手段】自動水栓１は、バッテリ８１と、バッテリ８１からの出力電圧を昇圧して出力する昇圧回路８２と、昇圧回路８２からの出力電圧に基づいて充電されるコンデンサ８３と、を備えている。さらに、自動水栓１は、コンデンサ８３から供給される電力に基づいて駆動する原水用センサ６０Ａ、浄水用センサ６０Ｂ、原水用開閉弁４０、及び浄水用開閉弁４２と、バッテリ８１から供給される電力に基づいて動作し、これらの負荷を駆動させる制御を行う制御回路７１と、を備えている。制御回路７１は、昇圧回路８２に昇圧動作を行わせるオン制御と、昇圧回路８２に昇圧動作を行わせないオフ制御と、を切り替える。【選択図】図２
