摘要： An object of the present invention is to provide a multi-layer glass with high degree of vacuum and high mass productivity. In order to achieve the object, the multi-layer glass according to the present invention includes a first glass substrate, a second glass substrate disposed facing the first glass substrate with a space therebetween, a sealing portion, which contains a glass composition and is disposed in a peripheral edge portion of the space between the first glass substrate and the second glass substrate, and column members disposed between the first glass substrate and the second glass substrate, wherein the column member is made of a metal or alloy, and a melting point of the metal or alloy is higher than a softening point of the glass composition and is lower than or equal to a temperature 20° C. higher than a flow point of the glass composition.
