CURRENT SENSOR

PROBLEM TO BE SOLVED: To provide a current sensor capable of maintaining excellent characteristics even if a conductive member through which measured current flows is downsized.SOLUTION: This current sensor (1) comprises: a conductive member (11); and galvanomagnetic elements (121, 122). The conductive member (11) includes a first flow part (111) through a fifth flow part (115). The galvanomagnetic elements (121, 122) are provided with sensitivity axes (S1, S2) arranged in the same direction. Connections (114h, 115h) on a third flow part (113) side are arranged so as to be outside of connections (114g, 115g) on the first flow part (111) side or a second flow part (112) side. A fourth flow part (114) and the fifth flow part (115) are provided with a distance (D12) between connections (114f, 115f) on the third flow part (113) side that is relatively larger than a distance (D11) between the connections (114h, 115h) on the first flow part (111) and the second flow part (112).
