PROBLEM TO BE SOLVED: To provide a flat nozzle for steam cleaning capable of resolving disadvantages that: when injecting steam with a nozzle, steam injected from the nozzle captures surrounding air, thereby rapidly decreasing a temperature of the steam to reduce a flow rate thereof; steam is contracted at a nozzle inlet portion and expanded in the nozzle, thereby reducing a flow rate at an ejection port in some flat nozzles; and hot water or a cleaning agent is mixed frontward of the nozzle, thereby not dispersing them uniformly. SOLUTION: In the flat nozzle for steam cleaning, the nozzle is made to have a vertical dividable structure, a slit gap of the ejection port is made small, and an area of flow path at a feed port, a feed passage, a recess or the like is made sufficiently larger than an area of a flow path at the ejection port (wherein an area of flow path at the ejection port is a product of the slit gap and a slit width), thereby contracting the steam at the ejection port, and a plurality of auxiliary agent pipes are disposed in the nozzle so that an auxiliary agent is fed nearly frontward of the ejection port to be uniformly dispersed.
