The invention relates to a vacuum glass, which comprises an upper glass and a lower glass, and is characterized in that the welding periphery of the upper glass is provided with an edge sealing strip frame, the welding periphery of the lower glass is provided with an edge sealing strip frame and an edge sealing ditch groove, and a glass welding material is adopted to integratedly weld the upper glass and the lower glass in a vacuum edge sealing furnace, such that vacuum glass manufacturing is simple, and a sealing effect is ensured through engagement of the edge sealing strip frame and the edge sealing ditch groove. The manufacturing method has characteristics of simple process, low cost, high production efficiency, reliable sealing and good sealing effect. With the technology, large mass manufacturing of the vacuum glass with no gas exhaust port through the one-step method can be achieved. In addition, with the method, the universal vacuum glass can be manufactured, and the tempered vacuum glass can be manufactured.
