Recently, because the micro-machine is noticed and electronic equipments are made much lighter and smaller, the demand for micro materials is increasing. 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, fatigue test method of the fine wire was developed, and the tensile strength tests and fatigue tests were carried out using the copper fine wire with 100オm as the material. As the results, we could get the S-N curve of copper fine wire. Therefore, it was found that the fatigue strength at 106 cycles was 85% of tensile strength. The fracture surface of fatigue test was similar to that of tensile test.
