This current sensor is provided with: a primary conductor (110) in which a current, i.e., a subject to be measured, flows; at least one magnetic sensor (120), which detects the strength of a magnetic field generated due to the current flowing in the primary conductor (110), and which has a detection axis; a substrate (130) on which the magnetic sensor (120) is mounted; and an arch-like magnetic material section (140), which is fixed on the substrate (130), and which surrounds the magnetic sensor (120). A pair of openings (140h) formed by fixing the magnetic material section (140) on the substrate are facing each other by being aligned in the direction of the detection axis. |
