## Abstract

A borosilicate glass for a pharmaceutical container having high appearance quality, particularly a small number of air lines, and a glass tube for a pharmaceutical container are provided. The borosilicate glass for a pharmaceutical container contains, in mass %, from 70.0 to 78.0% of SiO2, from 5.0 to 8.0% of Al2O3, from 5.0 to 12.0% of B2O3, from 0 to 4.0% of CaO, from 0 to 4.0% of BaO, from 4.0 to 8.0% of Na2O, from 0 to 5.0% of K2O and from 0.001 to 1.0% of SnO2.
