PROBLEM TO BE SOLVED: To provide a defect marking device for testing a painted surfaces of a vehicle, which can carry out marking defective positions by projecting a light beam thereon. SOLUTION: The marking device is mounted on an apparatus for testing the painted surface of the vehicle, which has a CCD camera 6 for scanning / photographing the outside painted surface of the vehicle and an image processing device 8 automatically detecting a microdefects generated in the painted surface from photographed signals. Plotters 15-19, which move a laser head 30 along the horizontal or the vertical two-dimensional scanning plane, thereby carrying out a light beam projecting plot in the horizontal or vertical direction, are mounted on a plotter mount cart 10, which is moved along a transport path in synchronization with a vehicle transportation, in a state in which the vehicle 1 whose painted surface test is finished is advanced therein. A plot controller stores two-dimensional defect position data as plot data produced by projecting a position of the micro-defect generated in the painted surface of the vehicle onto the horizontal or vertical two-dimensional projecting plane, retrieves the plot data sequentially, in response to switch operation and plots them on the painted surface of the vehicle.
