PROBLEM TO BE SOLVED: To provide a two fluid nozzle in which a 1st fluid is never mixed with a 2nd fluid in the nozzle. SOLUTION: In the two fluid nozzle structure for jetting the 1st fluid and the 2nd fluid in a mixed state to an objective space or an object, a 1st connection hole to which a base end part of an inside pipe is connected to communicate with a 1st fluid injection port and a 2nd connection hole to which a base end part of an outside pipe is connected to communicate with a 2nd fluid injection port are formed to communicate with each other in a nozzle base part, a 1st seal member for preventing the approach of the 1st fluid to a 2nd flow passage side and a 2nd seal member for preventing the approach of the 2nd fluid to a 1st flow passage side are provided between the outer peripheral surface of the inside pipe in the base end part side and the inner peripheral surface of the nozzle base part facing the 1st connection part and a communication passage for opening a space between the outer peripheral surface of the inside pipe and the inner peripheral surface of the nozzle base part facing the 1st connection hole to the outside is formed between the 1st seal member and the 2nd seal member.
