Abstract

PURPOSE: To perform a clear indication, by a method wherein laser is irradiated onto a thermoplastic material layer which transmits laser being laminated on a base material expanded due to absorption of laser, and a mark is indicated as the one embossed and formed in the projected shape.
CONSTITUTION: A thermoplastic material layer 14 (polyethylene film and the like) transmitting a laser light is laminated on a base material 12, such as boards, etc., generating a heat energy resulting from absorption of laser to form an object 10 to be marked. The laser 24 is irradiated onto the thermoplastic material layer 14 through a mask 20 to form a projected mark 26. This protects againt the indistinct indication of the mark 26 which may occur according to a light reflecting condition, and also permits the production of brailles and the like.
