PROBLEM TO BE SOLVED: To provide an apparatus for marking a defect, which can detect the defect in a long sheet product transferred to the longitudinal direction by using an inspection device, and can place a mark at the detected defect position by using an oil-based marking pen, without causing a decrease in the marking property due to drying of the tip of the pen. SOLUTION: In the apparatus for marking the defect, which detects the defect in the long sheet product transferred to the longitudinal direction by using the inspection device and places the mark at the detected defect position on the downstream side of the inspection device in the transfer direction, the mark is placed by the oil-based marking pen contained in an oil-based marking pen containing tube which has a shutter for closing the tip of the pen, and the shutter is opened on the basis of a signal sent from the inspection device, and the mark is placed at the defect position of the sheet product by the tip of the oil-based marking pen being pushed out, and then the oil-based marking pen is pulled back after the marking is completed, and the shutter is closed.
