Abstract
A temperature sensor, which is used particularly in the intake tube of internal combustion engines in conjunction with an air flow rate meter, includes a sensor element that is constructed as a temperature-dependent NTC resistor in the form of a pill, a cube or the like. A large number of identical temperature sensors are produced by applying a plurality of parallel conductor tracks, which include partial conductor tracks, to a glass plate or wafer, by providing the conductor tracks with outer solderable contact surfaces and inner solderable contact surfaces, by applying and electrically conductively connecting each sensor element to a first partial conductor track, by conductively connecting the sensor element to a second partial conductor track, by coating the sensor element with a resist layer, and by cutting apart the wafer with parallel cuts extending between the individual sensor elements.
