Abstract: The present invention relates to an apparatus for manufacturing vacuum glass. An apparatus for manufacturing vacuum glass, according to an embodiment of the present invention, includes an exhaust finishing frit inserted into an exhaust hole of a plate glass assembly so as to seal the exhaust hole in an exhaust process. In addition, the exhaust finishing frit comprises: a frit body having a body top part on which a cap frit is placed; a depressed portion which is upwardly depressed from the bottom of the frit body; and an exhaust guide part which is formed to penetrate the outer circumferential surface of the frit body. Thus, it is possible to prevent bubbles from being generated in the exhaust finishing frit during a finishing process.
