A method of producing a temperature measuring sensor including an insulating substrate having a top surface and a bottom surface, the top surface including a first area and a second area, and a first contact and a second contact being formed in the first area, the above contacts having a structured measuring film located therebetween: creating a conductive connection between the first contact on the top surface of the insulating substrate and the bottom surface of the insulating substrate, and a first conductive layer as a first terminal area of the temperature measuring sensor on the bottom surface such that the first conductive layer is electrically connected to the conductive connection, as well as a second conductive layer on the second area of the top surface as a second terminal area of the temperature measuring sensor such that the second conductive layer is in contact with the second contact.
