An automatic temperature control means 16 for automatically generating a mixed warm water of prescribed temperature by mixing an introduced hot water from a hot water inflow passage 14 and an introduced cold water from a cold water inflow passage 12 with each other at a flow rate ratio corresponding to the prescribed temperature, and a flow rate control means 19 for regulating the temperature of the discharged mixed warm water by mixing it with a hot or cold water introduced from the hot or cold water inflow passage 14 or 12 through a by-pass 18 around the former means are provided. As a result, mixed warm water of desired temperature can be easily obtained by manipulating the flow rate control means 19.
