PROBLEM TO BE SOLVED: To provide a faucet device in which the replacing time of a mounted water purifying means can be detected surely, installation works are simplified and facility after installation is improved. SOLUTION: A water supply pipe 9, which is connected to a water supply path 1a, to which an electronic faucet 18 opening and closing a pipe line is installed and in which raw water is passed, a water purifier 10, on which a water-purifying cartridge 12 purifying raw water introduced from the water supply pipe 9 is mounted, and a water spout pipe 15, which is connected to a drain pipe 14, in which purified water from the water purifier 10 is passed, and from which purified water is spouted, are set up. The faucet device has a main body section 21 with a built-in flow sensor for measuring the spouted amount of purified water, an operating means for operating water conveyance and water stop by the electronic faucet 18 and a control means 23 for controlling the electronic faucet 18 according to the signal of the flow sensor and the operation of the operating means and informing the lifetime of the water- purifying cartridge 12 from a preset integrating flow rate and the lifetime of the water-purifying cartridge 12 by the lowering of a water-spout flow rate detected by the flow sensor.
