The invention relates to an electrical resistor (1) comprising an electrically conductive stack (10), which comprises a plurality of metal first layers (12) and second layers (14). The stack 10 allows to produce a highly anisotropic resistor (1), in which the resistance in the direction perpendicular to the layers (12, 14) is much higher than in the plane of the layers (12, 14). The anisotropy allows the current flowing through the stack (10) to be made homogenous, i.e. to be distributed over the entire stack surface, even if the current is input into the stack (10) in an inhomogenous manner.
