The present invention relates to a current detection device, in particular a current detection device using a shunt resistor. The current detection device (30) includes a resistive element (5) and a pair of electrodes (6, 7). The electrodes (6, 7) have detection areas (24a, 25a) demarcated by first slits (16, 17), second slits (26, 27), and contact surfaces (6a, 7a) that at least partially contacts the resistive element (5). The electrodes (6, 7) further have voltage detection portions (20, 21) arranged in the detection areas (24a, 25a).
