PROBLEM TO BE SOLVED: To provide a trouble-free hot/cold water combination faucet with the function to purify water, that allows users to easily determine by simply viewing it whether it is delivering purified water or raw water. SOLUTION: The combination faucet includes a combination faucet body 2 and a shower head 3. The shower head 3 comprises a grip part 12 with a water purifying cartridge 11 built in, and a spout body 13 connected to the downstream end of the grip part 12. Further, the water purifying cartridge 11 holds a filter 14 inside a cylindrical cartridge case 15, and an annular raw water passage 90a and a purified water passage 90b are formed, respectively, outside and inside the filter 14. The spout body 13 has a raw water opening 36 allowing raw water to pass and a purified water opening 44 allowing purified water to pass, with the raw and purified water openings located respectively in upper and lower positions at the upstream end of the spout body. Also the spout body has a switch means for switching its state between a raw water discharge state in which the raw water is in communication with raw water discharge passages 202 and 203 after passing through the raw water opening 36, and a purified water discharge state in which the purified water is in communication with a puirified water discahrge passage 204 after passing through the purified water opening 44.
