A mixing valve comprises a valve body and a plurality of helical members. An agitation chamber is formed in the valve body. The plurality of helical members are disposed substantially in parallel in the valve body and have a number corresponding to a number of fluid supply ports. The plurality of helical members have helical passages on their outer circumferential surfaces and have ends facing the agitation chamber. Fluids are supplied from the fluid supply ports and pass through the helical passages.
