The invention discloses a heat-sensitive label which comprises heat-sensitive paper, wherein an isolation layer is coated on one side, opposite to a heat-sensitive coating, of the heat-sensitive paper; an ink layer with a preset diagram text is printed on the isolation layer; a glue layer is coated on the ink layer; release paper is bonded onto the glue layer. When the heat-sensitive label is used, the release paper is removed first, and then one side, with the glue layer, of the heat-sensitive label is adhered to a product, wherein the heat-sensitive paper is located on the surface layer, when the heat-sensitive coating is heated, the discoloration occurs so as to play the role of information indication and identification, when the heat-sensitive paper is removed, the ink layer is firmly adhered on the product under the action of the glue layer, and represents the preset diagram text so as to achieve a certain anti-counterfeit effect; the ink layer and the glue layer of the heat-sensitive label are unlikely to remove, so that the heat-sensitive label is more reliable.
