PROBLEM TO BE SOLVED: To provide a label for laser etching in which a desired color is easily made to appear on a label surface without strictly controlling an output of laser. SOLUTION: The label for laser etching which has at least a 1st colored layer 2 and a 2nd colored layer 4 formed under the 1st colored layer, and which is irradiated with a beam of laser to remove the 1st colored layer and expose the 2nd colored layer on the surface for printing letters, characterized in that a diffusion layer 3 for diffusing a beam of laser is formed between the 1st colored layer and the 2nd colored layer.
