Zusammenfassung:	To provide a borosilicate glass for a pharmaceutical container which does not include BaO, has excellent chemical durability and hydrolytic resistance, and in which excellent chemical durability and hydrolytic resistance may be maintained even after various thermal treatments at the time of converting process. There is provided a borosilicate glass for a pharmaceutical container including SiO 2 , Al 2 O 3 , B 2 O 3 , and R 2 O (R is one or more kinds selected from Li, Na, and K) as essential components, in which a content of CaO is equal to or greater than 0 and smaller than 0.5 mol%, a value of (Na 2 O + K 2 O + Li 2 O - Al 2 O 3 )/B 2 O 3 is 0.315 to 0.350 in terms of a molar ratio, and BaO is not substantially included.
