PROBLEM TO BE SOLVED: To provide a resin plate which contributes to the reduction in the amt. of the photosetting resin to be used and the shortening of a production time as compared with the conventional 2P process and its production. SOLUTION: This resin plate is composed of a photosetting resin layer 2 and is internally formed with a hollow 3 portion. The resin plate is produced by pouring the photosetting resin into a lower mold 11 arranged with a stamper 12, forming the photosetting resin layer 2, inserting and expandable and contractable mold 17 into the photosetting resin layer 2, expanding this mold and curing the photosetting resin layer 2 in this state. Next, the mold 17 is reduced and is removed from a disk mold 15. |
