An oxide glass that can be suitably used for a display panel or the like is provided. Oxide glass is expressed in terms of the ratio of other elements excluding oxygen among the contained elements. B is 55 atomic% to 85 atomic%, Si is 0 atomic% to 15 atomic%, Zn Is 0 atomic% to 15 atomic%, K is 0 atomic% to 10 atomic%, Na is 0 atomic% to 10 atomic%, Bi is 1 atomic% to 10 atomic%, and the total of Si and Zn is 5 The total of K and Na is 1 atomic% or more and 10 atomic% or less, and the total of K, Na and Bi is 8 atomic% or more and 15 atomic% or less.
