PROBLEM TO BE SOLVED: To provide a faucet device capable of suppressing a back flow of raw water to a side of a water purification part even when raw water discharge and purified water discharge at a water discharge part are alternated upstream from the water purification part and a raw water-side flow passage and a purified water-side flow passage join together downstream from the water purification part.SOLUTION: A faucet device includes: a raw water-side flow passage which supplies raw water supplied from a water feed source toward a water discharge part; a purified water-side flow passage in which a water purification part for purifying the raw water is interposed and which supplies purified water toward the water discharge part; and a flow passage change-over part which selects one of the raw water-side flow passage and purified water-side flow passage so as to supply the raw water. The water discharge part includes: a plurality of water discharge ports; a plurality of discharge water passages which supply the raw water supplied from the raw water-side flow passage to the plurality of discharge ports respectively; and a discharge style changeover part which makes a choice of which of the plurality of discharge flow passages the raw material is supplied to, the purified water-side flow passage joining one of the discharge flow passages downstream from the discharge type changeover part.
