Provided is a barium-silicide-based bulk polycrystalline body, a barium silicide-based film, and an application for the same. A barium-silicide-based bulk polycrystalline body characterized in that [M]/([Ba]+[Si]+[M]) is 0.01-20 atm% and the oxygen content is 20 atm% or less, where [Ba], [Si], and [M] respectively represent the amount of barium, silicon, and a metal element M (at least one element selected from the group consisting of strontium, calcium, and magnesium). |
