To provide a levitation air plate that can be easily manufactured and can float a substance being conveyed such as a glass while maintaining its high rigidity and controlling a floating amount in high accuracy. A levitation air plate 1 provided with: a top plate 2 in which a plurality of air ejection holes 2c and suction holes 2d penetrating from an upper surface 2a to a lower surface 2b are arranged in alternating fashion as viewed from the upper surface, the top plate 2 having a counter-bored portion 2e on the lower surface side of each of the plurality of air ejection holes; an orifice sheet 3 having a plurality of orifices 3c penetrating from an upper surface 3a to a lower surface 3b in positions corresponding to the counter-bored portions of the top plate, and having communicating holes 3d communicated one-to-one with the suction holes of the top plate and penetrating from the upper surface to the lower surface; and bottom side plates 4, 5 having an air supply channel 4c and an air supply hole 5c for supplying air to all of the orifices drilled in the orifice sheet, and an air suction channel 4d and a suction hole 5d for suctioning air from all of the communicating holes communicated with the suction holes. |
