Nanoindentation is used for evaluating the mechanical properties of micro material. However, it is not examined whether nanoindentation can apply to thin sheet. Therefore, the establishment of the test method for the thin sheet is necessary. In this study, SUS304 thin sheets with thicknesses of 100, 50, 20 and 10μm were used. Specimens were glued to metal block with using 2 kind of adhesive, Young's modulus and indentation hardness were measured. As the results, Young's modulus was almost constant in the low indentation load region, but that was decreased when indentation load is increased than a certain value. Indentation hardness was almost constant despite surface polishing or adhesive. But, in the case of thicknesses of 20 and 10μm, the effect of the thickness appeared in the hardness when indentation load is very large.
