PROBLEM TO BE SOLVED: To provide an effective dust protection method in the midst of laser marking treatment. SOLUTION: When an object 1 for treatment is subjected to laser marking using a laser marker 4, a film with adhesive 23 obtained by coating or providing a film 2 with an adhesive 3 is adhered to the object 1, thus the scattering of dust 6a from the treatment face in the object 1 is prevented. The dust 6a is stuck to the film with adhesive 23, and the film with adhesive 23 is subjected to laser treatment and is thereafter peeled. The film 2 is provided with sufficient transmissivity to the wavelength of laser beam 5 to a degree at which laser marking can be performed or above, and also, the adhesive 3 is the similar one.
