ABSTRACT OF THE DISCLOSURE The invention relates to a device for temperature measurements, comprising a temperature-sensitive sensor whose electrical properties, e.g. resistance, vary with the temper- ature, e.g. a thermistor, and which via two contacts is connected to two electric conductors arranged on a support, which electric conductors in turn can be connected to a reading unit for the reading of the actual values of current, voltage or the like corresponding to the temperature. In a preferred embodiment the said electric conductors are in the form of two metal layers, on both sides of a support made of plastics. The one metal layer is interrupted by a gap which is arranged to be bridged by the sensor, one contact of which is connected to each conductor. The invention relates also to a method for the manufacture of a device of the above-mentioned kind. A sheet of an electrically insulat- ing material, e.g. plastics, coated with metal on both sides, is by said method electrically short-circuited along one edge; a gap, slit or the like being provided parallel with this edge, and the sheet being cut into strips transversely to the short-circuiting and to the said gap, slit or the like with one contact connected to each metal coating.
