The present invention relates to a metal oxide sintered body for a temperature sensor, which is installed in a combustion engine and its connecting parts to sense a temperature, and a method of manufacturing the metal oxide sintered body. The metal oxide sintered body has a high resistance characteristic, To a sintered metal oxide. Since the metal oxide sintered body manufactured according to the method of the present invention is mixed with particles having a large resistance value and particles having a small resistance value, particles having a small resistance value become a main resistance component in a temperature range of 0 ° C to 500 ° C, At a high temperature of -900 캜, particles having a large resistance value contribute to the total resistance by a mixing ratio, thereby increasing the overall resistance value. Therefore, all the resistance measurement, that is, the temperature measurement can be performed by one sensor in a temperature range from 0 ° C to 900 ° C, so that it can be used for an automobile exhaust device requiring a wide range of temperature measurement. |
