Abstract: A resistive layer with the elements nickel, chromium, aluminum, cooper and silicon has a low temperature coefficient and a high degree of long-time stability. The copper content is to 5.5 weight-% and the silicon content is 0.5 to 1.6 weight-%, respectively in relation to aluminum, and the ratio of Ni: Cr: AlSiCu is within a range which is defined by a hexagon ABCDEF shown in FIG. 1, the corner points of which are provided by the following compositions in weight-%:______________________________________ A 58 Ni 40 Cr 2 AlSiCu B 52 Ni 33 Cr 15 AlSiCu C 32 Ni 33 Cr 35 AlSiCu D 13 Ni 52 Cr 35 AlSiCu E 13 Ni 75 Cr 12 AlSiCu F 18 Ni 80 Cr 2 AlSiCu.
