A method for producing a laminated object repeats a depositing step and an irradiating step alternatively. The irriating step comprises the operations of: covering a deposited layer with a mask having a pattern configuration for penetrating the laser beam; and scanning the lader beam on the desposited layer covered with the mask in such a manner that the laser beam depicts an irradiated continous wave trace being wider than the pattern configuration of the mask, by moving the laser beam in the Y-direction with a Y-rotating mirror, while repeating oscillations of the laser beam in the X-direction with a X-rotating nirror, The laminated object may be a casting mold.
