PROBLEM TO BE SOLVED: To inject a gas/liquid mixing mist with strong hitting force from a two-fluid nozzle used as a washing nozzle. SOLUTION: A main flow passage fed with a gas and a liquid feed passage opened to a peripheral surface of a gas/liquid mixing part provided on the main flow passage are provided on a nozzle body. The liquid fed from the liquid feed passage is mixed to the gas circulated in the main flow passage by side surface collision. An injection side distal end of the main flow passage for circulating the gas/liquid mixing fluid mixed at the gas/liquid mixing part to the injection side is made to a closure part made to a flat surface or a circular surface. A dome-like main hole gradually made to a small diameter toward an apex of a center and having an axial cross section becoming a circular shape is provided at the inside and the main hole is communicated with the main flow passage to make the mixing fluid flowing. A radial cut-in part is provided on the closure part at the injection side distal end with a predetermined clearance from an outer peripheral edge. The cut-in part is inclined in a depth direction directed from both ends in a longitudinal direction toward the center and a central part of the cut-in part is communicated with a distal end side of the main hole. A slit-like injection hole spread in a taper shape toward the injection side outer surface is provided making a communication position with the main hole as an inner end. COPYRIGHT: (C)2006,JPO&NCIPI
