Provided are an information recording label, a printing sheet and their authenticating method, which can perform an authentication highly strictly. The information-recording label is formed to include a protecting layer (1), an intermediate layer (2), metal layers (5, 6) and an adhesive layer (4). The protecting layer (1), the intermediate layer (2) and the adhesive layer (4) are made of a dielectric material having a predetermined dielectric constant. Of the metal layers, the first metal layer (5) is arranged in a circle in a conductive layer, and the second metal layer (6) is arranged in such a shape that its longer sides to resonate with a predetermined frequency when measured by a microwave sensor are arranged on the two sides of the first metal layer (5) with a length of 1/2n (n: an integer of 0 or more) of a predetermined wavelength. The protecting layer (1), the intermediate layer (2) and the adhesive layer (4) are arranged in an elliptical shape larger than the metal layers. When this information-recording label is measured by using a leakage microwave sensor, the detected voltages indicate an intermediate level in the conductive range of the first metal layer (5), a high level in the conductive range of the second metal layer (6), and a low level in the remaining ranges.

An examination method and instrument for examining the defect of a provided OVD and the position where the OVD is provided without being influenced by a variation of the pattern of the OVD due to flapping or waving during transfer of a printed sheet. Image input means and illuminating means are disposed at positions where the light specularly reflected from the OVD and the light diffracted at the OVD are the threshold or less in binarization by image processing means, respectively. The surface of a base is illuminated with infrared rays or light containing infrared rays by the illuminating means. The image input means inputs image data including a wavelength region above 650 ⏧nm] about an area including the OVD provided to the base. In a storage means, reference image data on the reference OVD alone or both the reference image data and data representing the reference position are previously stored and the inputted imaged data are further stored. Image processing means performs binarization, compares the image data with the reference image data, or compares the image data with the reference image data or the data representing the reference potion, and judges whether of not at least one of the shape, area and position of the OVD provided to the base on the basis of the results of the comparison is acceptable.
