To provide a labeled object for a CCD camera capable of inhibiting trouble in discriminating shade by the CCD camera even when defacement advances, enhancing reliability of image data taken by the CCD camera, preventing malfunctions in systems and generation of inferior goods, mitigating maintenance, and preventing decrease of an availability factor of an apparatus of a position-detection object to improve productivity.

The labeled object 1 for a CCD camera, imaged by the CCD camera for acquiring position information of a position-detection object, includes a labeled object body 8 which is installed in the position-detection object, a straight hole 9 which is formed in the labeled object body from its surface portion 8a toward inside, a tapered recess 10 which is formed in the labeled object body so as to be continuously connected to the straight hole and has a reflecting slope 10a inclining to an optical axis X of the CCD camera to attenuate light x1 entering the straight hole, and a light reflecting surface 12 which is formed at a surface portion of the labeled object body to surround an opening of the straight hole.
