Abstract

The invention relates to a resistance measuring element (20) formed with an elongated metal material, wherein high-current connections (21, 22) are formed in the region of its ends, and which is provided on one side that is to be connected to a circuit carrier substrate with at least two voltage measurement press-in pins (24) which are arranged at a defined distance from one another, the metal material having a predefined cross-section and a predefined specific resistance between the press-in pins (24). The invention also relates to a current measuring circuit comprising such a resistance measuring element (20) and a temperature sensor (26).
