Provided is a current sensor wherein cost is suppressed and size is reduced. A current sensor (1) has: a bus bar (3) in which a current (2) to be detected flows; a core (4), which surrounds the bus bar (3), and has a gap (40) formed in a part thereof; a Hall element (54), which is disposed in the gap (40) in the core (4), detects a magnetic flux (25) in the gap (40), said magnetic flux being generated due to the current (2) flowing in the bus bar (3), and outputs a non-linear detection signal (S1) in a region where the magnetic flux (25) in the core (4) is magnetically saturated; and a control unit (55) that converts the non-linear detection signal (S1) into a linear conversion signal (S2), said non-linear detection signal having been outputted from the Hall element (54). |
