PROBLEM TO BE SOLVED: To provide a one-hole-type hot-water branched combination faucet which realizes cost reduction, and can prevent flowing of hot water at a temperature of 70 deg.C or more to a dish washer drier. SOLUTION: The one-hole-type hot water-branched combination faucet is constructed in the following manner. A water/hot water combination faucet main body V including a handle lever 3 for adjusting the mixture ratio of water and hot water and adjusting the water spout amount inclusive of water cut-off, and a spout pipe 2 for mixed water and hot water, has a water inflow bore 14 and a hot water inflow bore 13 formed therein, to which a water supply pipe 6 and a hot water supply pipe 7 are connected respectively. While the water supply pipe 6 and the hot water supply pipe 7 are inserted into a single through hole 8 formed in a faucet installation plate 5 of a sink or the like in a kitchen, the combination faucet main body is installed on the faucet installation plate. Then, a hot water branch valve 30 for branching part of hot water flowing into the hot water inflow bore via the hot water supply pipe and directly connecting a hot water branch passage E to a hot water inlet port of the dish washer drier 20, is arranged in the combination faucet main body. According to the combination faucet, a hot water preventive valve 31 for preventing hot water at a predetermined temperature or more from flowing out to the dish washer drier, is arranged across the hot water branch passage.
