<p>The present invention provides a classification mark in which adhesion is facilitated, fixability after adhesion is stronger, and precise adhesion to a desired position without twisting is enabled. In order to implement this, the classification mark of the present invention comprises: a bottom plate in which a fixing adhesive layer and an adhesive layer are coated on both sides on a flat surface while interposing an adhesive-uncoated surface therebetween, an adhesion guide line is formed along the outer periphery, an adhesive layer is coated on a back surface, and the adhesive-uncoated surface is formed along an outer edge surface; a cover plate made of a transparent material, covered on the upper surface of the bottom plate in a spreadable manner in which a fixing adhesive layer to be adhered and fixed to the fixing adhesive layer of the bottom surface and an adhesive layer are coated on a back surface, respectively, an adhesion guide line is formed along the outer periphery, an opaque classification window border is coated along the outer periphery on a flat surface, and a transparent classification window is formed at the center; and a classification plate adhered and fixed to the adhesive layers coated on the flat surface of the bottom plate and the back surface of the cover plate while being inserted between the bottom plate and the cover plate in which a letter, a number or a symbol is marked on a flat surface, and an adhesion guide line is formed on the outer peripheral surface.</p> |
