PROBLEM TO BE SOLVED: To obtain an ultrasonic inspection method in which the consistency and the reliability of an inspection are enhanced by providing a female mold face which is molded so as to match with the shape of a face to be inspected, on a three-dimensional shape molding and installing a printing means which indicates an inspection point so as to overlap the face to be inspected on the female mold face. SOLUTION: A marking jig 1 (in the following, described as a stamp) is provided with a female mold face 2 which is molded so as to match with the three-dimensional shape of a face to be inspected, on a wing for a gas turbine engine as an object to be inspected. A plurality of protrusion parts 3 which print marks used to indicate inspection points on the face, to be inspected, so as to be overlapped with the face to be inspected are formed on the female mold face 2. Before a coloring material such as a paint, an ink or the like which is applied on the protrusion parts 3 is dried, the female mold face 2 faces the face to be inspected, on the object to be inspected, and the blade is made to overlap the stamp 1. The coloring material which is applied on the protrusion parts 3 is transferred to the face to be inspected, and the marks which indicate the inspection points are printed on the face to be inspected. After the coloring material is dried, an inspection probe is brought into contact according to the marks by handwork, and an ultrasonic inspection is executed regarding the respective inspection points.
