PROBLEM TO BE SOLVED: To solve the problem at a place having a narrow working space wherein working efficiency may be remarkably lowered and water jet may not be jetted to a portion to be cut, by a cutting device using water jet that jets water along the axial direction of a nozzle. SOLUTION: The cutting device using water jet to perform cutting by jetting high pressure water includes a body connected to a high pressure hose through a swivel joint disposed at an end portion; the elongated nozzle disposed at the distal end of the body; a nozzle head disposed at a jet port orthogonal to the shaft of the elongated nozzle; a rotary actuator for oscillatingly rotating the elongated nozzle around an axis; and handles disposed on both sides of the body, respectively.
