In a method for producing a temperature sensor, there is first provided a substrate, on the first surface of which there is arranged a sensor structure having a first end and a second end, wherein the sensor structure substantially completely covers the first surface of the substrate. Then an insulation layer is at least partially formed on this sensor structure on which a first and a second contact area are then formed. The first and second contact areas are formed such that they are conductively connected to the first end and the second end of the sensor structure, respectively.
