To produce an electrical measuring resistor having a predetermined temperature coefficient for a resistance thermometer, a substrate made of aluminium oxide ceramic is provided with a thin platinum film, to which a layer composed of a preparation which contains platinum resinate and rhodium sulphoresinate and whose rhodium content governs the desired temperature coefficient is then applied by screen printing. After drying and baking said screen-printed layer, the substrate coated in this way is subjected to heat treatment at a temperature in the range from 1000 to 1400 DEG C until the rhodium is uniformly dispersed in the previous platinum resistance layer or the resistance layer being formed.
