As the amine-based catalyst 4, ammonia gas and amine- based compound with catalytic activity are normally used. After that, through the exposure 5 of the whole surface of the board, the part, which is not irradiated by laser beams, is turned to be made soluble to developer so as to produce reversal resist pattern 6 through developing treatment. Etching is performed by utilizing the resist pattern 6 as mask so as to cut off the exposed part of the board in order to produce pattern and chip the remaining resist pattern, resulting in producing a transparent stamper 7. An optical disc board 10 is manufactured by irradiating light from both sides of photosetting resin 9, which is interposed between the transparent stamper 7 and a transparent keep plate 8, so as to set the resin.
