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 10 and 20μm were used. Specimens of which three kinds width are 0.1, 0.5, 2mm and three kinds of angle between rolling direction and loading axis are 0, 45, 90° were manufactured using etching method, and tensile strength tests were carried out. As the results, it was seen that tensile strength decreased with decreasing the width of specimen. Moreover, Young's modulus and tensile strength of the specimens that are different from angle between rolling direction and loading axis was affected by rolling direction.
