Nickel electroforming is used as a fabrication technology of micro metal mold including LIGA process. However, neither the strength nor peelability of electroformed nickel is enough. There are several methods to improve strength of the metal mold - alloying, and using additive composition of electroplating bath, for example. In this research, we improved the hardness of the metal mold by electroforming on hard and thin nickel electroplating. We used sodium allylsulfonate as an additive for hard nickel electroplating. The hardness was approximately 600 Hv and kept the property after annealing of temperature 250 ℃. The abrasion resistance was approximately 41WR after annealing of temperature 250 ℃. Finally, we fabricated nickel mold has micro pattern and the thickness of 4 mm.
