PROBLEM TO BE SOLVED: To obtain a high pressure fluid jet nozzle capable of improving a burr removal performance or a cleaning performance by jetting a high pressure fluid from wide directions, and to provide a burr removal apparatus and a cleaning apparatus. SOLUTION: The high pressure fluid jet nozzle 21 is used for the burr removal apparatus or the like. Jetting nozzles n1, m1 for jetting the high pressure fluid supplied to a cylindrical nozzle main body 23 are provided on at least two standard circumferences C<SB>2</SB>, C<SB>2</SB>for nozzle arrangement which are away from each other in the center axis direction across an impact standard surface P<SB>0</SB>orthogonally crossing the center axis of nozzle main body 23 on the outer circumferential surface of the nozzle main body 23. In each jetting port n1, m1 equipped one each standard circumference C<SB>1</SB>, C<SB>2</SB>for nozzle arrangement, a fluid jetting angleθ<SB>1</SB>,α<SB>1</SB>are respectively set to shoot the high pressure fluid on or near an impact circumference Cp almost concentric to the nozzle main body 23 on the impact standard surface P<SB>0</SB>.
