Abstract
A glass for laser processing of the present invention can be laser-processed by causing ablation or evaporation by laser beam energy absorbed therein, wherein the glass for laser processing has a composition that satisfies the following conditions:60≦SiO+BO≦79 mol %;5≦AlO+TiO≦20 mol %; and5≦LiO+NaO+KO+RbO+CsO+MgO+CaO+SrO+BaO≦20 mol %,where 5≦TiO≦20 mol %. The present invention can provide a glass for laser processing that has a low laser processing threshold value as well as a low thermal expansion coefficient.
