PROBLEM TO BE SOLVED: To provide a method for manufacturing a stamp seal face with which a manufacturing process may be easily and smoothly carried out, the reduction of a manufacturing cost and the improvement in the exactness of exposure may be achieved and plural stamp seal faces may be simultaneously subjected to an exposure stage and an exposure device used for the same. SOLUTION: This process consists in successively carrying out a stage for mounting sponge-like seal face rubber 31 to a holder 30 and injecting ink thereto to form semi-finished goods of the stamp, a stage for preparing a negative film 32 formed with prescribed seal face patterns by a photomechanical process, a stage for fixing he semi-finished goods of the stamp mounted with the seal face rubber 31 to an exposure device 1, a stage for aligning the negative film 32 onto the seal face rubber 31, a stage for installing and fixing a glass sheet 34 onto the negative film 32 and a stage for forming the seal face patterns on the seal face rubber 31 by projecting a flash on the negative film 32 and exposing the seal face rubber 31.
