Abstract
Disclosed herein is an apparatus for manufacturing an optical substrate which has a transfer layer corresponding to an optical pattern by supplying a liquid radiation-setting resin between a stamper carrying the optical pattern and the substrate and by setting the radiation-setting resin. The apparatus includes a turnable, a center boss, gas pressure control mean, and a defoaming means including an outer circumferential means to defoam the radiation-setting resin. The turnable, the center boss and the gas pressure control means are united into a carriage base which is movable on the casing of the apparatus.
