Provided is an abrasive water jet nozzle comprising a mixing chamber for absorbing the abrasives with air through a supply port; a water nozzle; a mixing nozzle disposed on the downstream side against the water nozzle, to mix the abrasives in a water jet jetted out of the water nozzle, and to jet the water jet into the mixing chamber out of a through hole of the mixing nozzle; and an abrasive nozzle disposed on the downstream side against the mixing nozzle, to introduce the water jet thereinto to jet an abrasive water jet. A diameter of the through hole is larger than that of the water nozzle so that the abrasives in the mixing chamber are absorbed with air in a clearance between the through hole and the water jet passing through the through hole to mix the abrasives in the water jet.
