PROBLEM TO BE SOLVED: To provide a high-pressure jet nozzle which can easily be produced and of which the durable life is extended and the liability of the operation is improved. SOLUTION: The high-pressure jet nozzle for flowable medium has a nozzle body 1, a nozzle disk 2 which is buried in the recessed part 7 of the nozzle part 1, made of a high-strength material, communicating with inlet and/or outlet holes 4, 5, and preferably has a nozzle hole 3 in the direction of an axis at the center. Then the nozzle, that is, the nozzle for generating the high-pressure jet of a flowable medium, is designed so that the nozzle disk 2 may be supported by the contact surface of the recessed part 7 receiving a compression strain.
