NTC thermistor is used as temperature sensor which would be hold in severe temperature environment. We must need to know not only electrical properties but also mechanical properties in the sever conditions. In this paper, we study mechanical properties and resistance to thermal shock of poly-crystal semiconductor. After doing tensile tests of 4 types of materials with different ratio of compounding, we clarified the difference of mechanical properties for these properties. Choosing one type of thermistor specimens, we have done thermal shock test and evaluate the Young's Modulus and flexural strength of NTC thermistor from the view point of composite.
