The invention provides vacuum glass and a manufacture method thereof, characterized in that micro-salient-point supporting objects melted together with an original glass sheet are used to substitute for a traditional stainless steel supporting object distributing process, a low-temperature metal braze-welding technology without causing the anneal of the original toughened glass sheet is used for sealing edges, and a traditional vacuum-layer vacuumizing process and an edge-sealing process are simplified and integrated into an integrated vacuumizing and edge-sealing process. Compared with traditional vacuum glass and the manufacture method thereof, the vacuum glass and the manufacture method thereof, which are provided by the invention, have simple process, high yield, low equipment investment and production cost, better heat and sound insulation, better appearance and light transmittance, high safety reaching the use standard of high-rise buildings, and the like.
