| description | The present invention provides a glass composition that allows holes with a circular contour and a smooth inner wall to be formed by a collective micro-hole-forming process using a combination of modified portion formation by ultraviolet laser irradiation and etching, the glass composition being adapted for practical continuous production. The present invention relates to a glass for laser processing, the glass including a metal oxide serving as a coloring component, the glass having a glass composition including, in mol %: 45.0%≤SiO2≤68.0%; 2.0%≤B2O3≤20.0%; 3.0%≤Al2O3≤20.0%; 0.1%≤TiO2≤5.0%; and 0%≤ZnO≤9.0%, wherein a relationship of 0≤Li2O+Na2O+K2O |
