Provided in the present invention is a vacuum glass, comprising: a plurality of plate glasses arranged to be spaced apart at fixed distances; a sealing material provided along edges of the plate glasses to seal and adhere to the plate glasses; and a plurality of pillars arranged between the plate glasses to maintain the distances between the plate glasses. The plurality of pillars are arranged at different arrangement distances in vertical and horizontal directions. Thus, the thermal insulation performance of the vacuum glass may be improved, and stress applied to the vacuum glass may be reduced by the pillars to secure the safety of a product.
