A metal-oxide sintered body for a temperature sensor that can be installed in a combustion engine and components connected to the engine in order to sense temperature uses metal oxide. The metal-oxide sintered body has particles with large resistance values and particles with small resistance values mixed therein. The particles with the small resistance values may serve as a main resistance component in the temperature range of 0&#xb0; C. to 500&#xb0; C., and the particles with the large resistance values may contribute to the total resistance in proportion to the mixing ratio in the temperature range of 500&#xb0; C. to 900&#xb0; C. Thus, the metal-oxide sintered body enables a single sensor to measure all resistances, and can be used in an exhaust device or the like of a motor vehicle that requires temperature measurement over a wide range of temperatures.

Metal-oxide sintered body for temperature sensor, and method for manufacturing same

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&#xb0; 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.
