<p>A method of processing a fragile material, comprising the steps of pre-setting the light (for example, laser beam)(L) absorptivity of a processed fragile material (W), calculating the absorptivity of a sample (S) provided when the light (L) of the same wavelength for the fragile material is radiated to the sample (S) by using the thickness of the plate-like sample (S) of the same material as the processed fragile material (W), selecting a light wavelength suitable for the absorptivity of the processed fragile material based on the calculated value of the absorptivity and the actually measured data of the absorptivity provided by actually radiating the light (L) to the sample (S), and processing the fragile material (W) by using the light of the selected wavelength.</p> |
