Abstract
A composite material for a temperature sensor and a method of manufacturing the temperature sensor using the composite material are provided. The composite material contains four or more kinds of metal oxides combined with highly insulating materials to produce a material with semiconductor-like properties to more accurately measure a temperature at high temperatures in the range of 500° C. and above. The sensor includes electrode wires having a predetermined diameter inserted into the metal oxide of the temperature sensor when the metal oxide is press-molded to form the temperature sensor. Through the connection of the electrode wires to the temperature sensor device, disconnection of the electrode wires from the device even at a high temperature.
