A glass plate conveyance pallet with good operability, where, even when glass plates are vertically layered on the conveyance pallet, no sag occurs about the center of the glass plates and sliding between the glass plates does not occur even in movement. Because a center bar (10) is made to be in contact with the vicinity of a central section (17a) of a cover body (7) covering glass plates (17) that are vertically layered, sag in the vicinity of the central section (17a) of the individual glass plates (17) that are layered and supported can be suppressed by the center bar (10). As a result, even during transfer of the conveyance pallet (1), movement of the layered and supported glass plates (17) is reliably prevented to prevent breakage of the glass plates (17). Further, the fixation and release of the layered and supported glass plates (17) by the center bar (10) can be made by swing motion of a support arm (9), so that operation is easy and, even if the number of layers of the glass plates (17) is increased or decreased, such a change can be easily coped with by changing the swing radius of the center bar (10).
