PROBLEM TO BE SOLVED: To surely improve injection characteristic of an injection nozzle by forming a vortex flow producing section at an injection hole through which fluid passes. SOLUTION: The injection nozzle 11 is equipped with injection holes 12, 36, 12a, 36a, 51 for injecting the fluid and the vortex flow producing sections 15, 15a, 38, 38a, 53 for giving vortex flows to the fluid passing through the inside of the injection holes 12, 36, 12a, 36a, 51 are respectively formed at inner wall surfaces of the injection holes 12, 36, 12a, 36a, 51.
