PROBLEM TO BE SOLVED: To provide an automatic water-sprinkling faucet which does not need a battery exchange and a wiring for supplying an electric power from an outer electric source, can be driven even with a small solar battery, and can simply be set to a water-sprinkling mode, a watering mode or the like. SOLUTION: In this automatic water-sprinkling faucet, an electric powder generated by the power-generating power of a solar battery is charged in a secondary battery to prepare an electric source for the faucet, and the power consumption of a control circuit is saved to ensure the electric source not related to the change in the percentage of sunshine. Water can automatically be sprinkled at a time measured by the detection of a sunrise.
