Recently, because the micro-machine is noticed and electronic equipments are made much lighter and smaller, the demand for micro materials is increasing. The researches for elucidating the mechanical properties of micro materials have been carried out. However the mechanical properties data of the micro materials obviously run short and the evaluation method of micro materials is different according to the researcher. Therefore, the establishment of the test method for the micro materials is very necessary. In this study, SUS304 thin sheets which thicknesses are 20μm were used. Specimens were manufactured using electrospark machining method and photo-etching method, and fatigue tests were carried out. As the results, it was seen that fatigue lives of electrospark machining specimens and photo-etching specimens were the identical order. The fatigue crack origins were inside and side of specimen.
