PURPOSE: To provide an apparatus for production of the optical disk substrate capable of nearly completely removing the static electricity on the surfaces of the optical disk substrate, preventing the sticking of dusts and improving the yield of post stages.

CONSTITUTION: The removal of the static electricity from the surfaces of the substrate 4 after taking the substrate 4 out of metal molds 2, 3 is conducted by two stages; a first static electricity removing stage (a static electricity removing stage 6 for the information surface and a static electricity removing stage 9 for the laser incident surface) and a second static electricity removing stage 18 with the apparatus for production of the optical disk substrate having a recording layer with which recording and reproducing of information are optically conducted. The removal of the static electricity is conducted dividedly by the two stages in such a manner, by which the electrostatic charge quantity of the substrate surfaces is nearly completely removed. The sticking of dust is thus eliminated and the yield of the post stages is improved.
