Recently, the early stage degradation of concrete structure becomes a subject of discussion. Electric resistance method is one of the non-destructive investigation to investigate the early stage degradation. However, electric resistance method has a large error when measurement by high temperature is performed. Then, when performing measurement by high temperature, it is necessary to improve the error. In this research, two terminals method was applied to measurement. And fundamental investigation about the electrical property of concrete was conducted. In the experiment, mortar was used as a sample. And the resistivity of mortar was calculated at various temperature. From the experiment result, the validity of the measurement which applied two terminals method was able to be confirmed
