Abstract
A supporting shaft 11 that can be inserted through a center hole 5a in each of cured resin disks 5 and which has a bottom plate in a disk form at an end, as well as a plurality of spacer disks 12 each having a center hole through which the supporting shaft 11 can be inserted are used in the process of manufacturing GC (glass-like carbon) by baking to carbonize the cured resin disks 5. The cured resin disks 5 are stacked alternately with the spacer disks 12 on the supporting shaft 11 in an erect position that is inserted through the center holes in each of the cured resin and spacer disks. The stack is then baked in a baking furnace. By so doing, the cured resin disks can be set up easily and the baking furnace can be operated to its full capacity.
