The present invention discloses a vacuum plate and a method for manufacturing it. The vacuum plate comprises at least two layers of plate, a plurality of support structures with different heights, and an organic film. The plates in adjacent layers are separated by a plurality of the support structures with different heights, peripheries of the at least two layers of plate are connected and sealed via a sealing mixture; and the peripheries of the at least two layers of plate and the outside of the sealing mixture are covered with the organic film. According to surface undulation of the plate, the supporting structures with corresponding heights are arranged on corresponding positions between the layers of plate, and the heights of the support structures match with the spacings at corresponding positions in the vacuum plate, so that each support structure can be clamped by the upper and the lower plate layers, and effectively plays a supporting role, thereby reducing the security risk from damage of the vacuum plate.
