PROBLEM TO BE SOLVED: To provide a cleaning nozzle which can be heated up to a temperature at which a necessary cleaning ability can be obtained, has a sufficiently high cleaning power to an extraneous matter on a surface of solid material, does not require a large size facility for exhaust after the cleaning and can complete the cleaning treatment in a short time. SOLUTION: The cleaning nozzle 1 for generating self-generation two fluids F obtained by boiling heated and pressurized water under an ordinary pressure comprises: an orifice part 2 provided with a flow channel for controlling a flow rate of the heated and pressurized water; an expanded diameter part 3 which is formed on the downstream side of the orifice part 2 and has a cross-section area of the flow channel of the orifice part 2 expanded therein to produce self-generation two fluids F; and a rectifying part 4 which is formed on the downstream side of the expanded diameter part 3, is provided with a flow channel having a cross-section area larger than that of the orifice part 2 and guides the self-generation two fluids F to the downstream side.
