PROBLEM TO BE SOLVED: To conduct mounting in a narrow space, provide the functions of water stop, branching, and passage selecting functions and attain a simple structure by providing an outflow port to a subsidiary function and a hot water source, an inflow port from the secondary piping of the subsidiary function and water supply outflow passage for communicating circulation water from the subsidiary function with the second faucet body part. SOLUTION: A branch faucet 1 is provided with an outflow port 20 pipe-laid to a subsidiary function, a water source and the like, and an inflow port 21 connected from the secondary piping of the subsidiary function. A ring packing 5 is fixed at the end part of an inner tube 4 of a branch faucet body part 18 to be connected to a water supply inflow port 6 of a faucet body part 24. An O-ring 19 is installed on the inner tube 4, and the inner part of the branch faucet body 18 is divided into the side of the outflow port 20 and the side of the inflow port 21. Therefore, the water flowing into the inner tube 4 through the water supply inflow part 6 flows into the outflow port 20 through the inner tube cutout part 35 from the inner tube opening 7, flows into the subsidiary function and then flows into a water supply outflow pipe 3 through the outside of the inner tube 4 from the inflow port 21.
