The invention relates to an electronic component (1), in particular a current sensor, having a resistance element (5) made of a resistance material, a first connection part (3) made of a conductor material for introducing an electrical current into the resistance element (5), and a second connection part (4) made of a conductor material for discharging the electrical current from the resistance element (5). According to the invention, the component (1) has a temperature-measuring device (8) for measuring a temperature difference between the resistance element (5), on the one hand, and at least one of the two connection parts (3, 4), on the other hand, in order to derive the current from the temperature difference.
