    Abstract: An object of the invention is to provide a multilayer glass which can be manufactured by a simple process. To solve the above problem, the multilayer glass according to the invention includes a first glass substrate, a second glass substrate that faces the first glass substrate at an interval of a predetermined space, and a sealing part that seals a periphery of an internal space defined by the first glass substrate and the second glass substrate. The sealing part is formed with a sealing material containing low melting point glass. The internal space is in a vacuum state. The first glass substrate includes an exhaust port that is provided to be included in a projection part of the sealing part when being projected in a lamination direction of the first glass substrate and the second glass substrate. The exhaust port is blocked by the sealing material (see FIG. 3).
