Therefore, the structure of each part can be further simplified and further miniaturized as compared with the case where the hot water supply part 10 and the water supply part 20 are directly connected to the main body part 30.

Further, the hot water supply unit 10 is formed by branching so as to supply hot water to each of the hot water flow passage HM for mixing and the hot water flow passage HD for discharge. Therefore, the structure of the main body 30 can be further simplified and further miniaturized as compared with the case where the hot water flow passage HM for mixing and the hot water flow passage HD for discharge are branched in the main body 30. Can be planned.

Further, the hot water flow passage HP on the discharge pipe side, which is connected to the main body 30 and communicates with the hot water flow passage HD for discharge, and the hot water flow passage on the discharge pipe side, which communicates with the hot water flow passage M. The discharge pipe 40 in which the MP is formed is provided. As a result, hot water and mixed hot water or water can be discharged with one discharge pipe, so that a discharge pipe for discharging hot water and a discharge pipe for discharging mixed hot water or water are provided separately. Further miniaturization can be achieved.

Further, the main body portion 30 is covered with a cover member 3 whose surface is a design surface. The main body 30 has a mixing valve 31 and a housing 32 in which the mixing valve 31 is housed and the hot water flow passage M and the hot water flow passage HD for discharge are formed. For this reason, the mixing faucet 1 is secured by a separate cover member 3 for the design, and for the main body 30, the storage form of the mixing valve 31 and the formation form of the respective flow passages HD and M are selected. For example, it can be arbitrarily performed from a viewpoint different from the design such as functionality. As a result, it is possible to easily realize a mixing faucet having other performances such as design and functionality.
