Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which a concave defect on the rear of a glass substrate is detected, by a method wherein the glass substrate is turned relatively in a state that light is obliquely incident on the surface of the glass substrate and a bright part which disappears and appears due to its rotation is detected when the bright part is viewed from a direction which is faced nearly with the surface. SOLUTION: In order to detect a defect on a glass substrate 1 which is used for an HDD or the like, e.g. the substrate 1 is placed on a rotary stage, and the surface of a rectangular region D is irradiated with oblique light L at an angle of incidence of preferably 45 to 70 deg.. The image of the rectangular region D is photographed by a CCD camera or the like which is installed so as to be faced nearly with the substrate 1, and the image is displayed, e.g. on a monitor. When a concave defect exists on the rear of the substrate 1, the incident oblique light L is reflected by the side face of the defect so as to be confirmed visually as a bright part on the screen of the monitor. The bright part disappears when the direction of reflected light is changed due to the rotation of the substrate 1.  By a prescribed method, all defects on the surface of the substrate 1 are detected the substrate is then turned over, and the concave defect on the rear is detected. Then, the concave defect can be discriminated from remaining convex defects.
