The utility model provides a current sensor capable of detecting current with high precision. A current sensor (1) is provided with: a plate-shaped bus bar (2) through which a current to be detected flows in the longitudinal direction; and a case (3) for holding the plurality of bus bars (2) in a state of being aligned in the width direction. A plurality of magnetic detection elements (4) that areprovided so as to face the corresponding bus bars (2) in the thickness direction and that detect the intensity of a magnetic field generated by the current flowing through the bus bars (2); and a substrate (5) on which the plurality of magnetic detection elements (4) are mounted. The substrate (5) is disposed so as to sandwich the plurality of bus bars (2) between the substrate (5) and the case (3) and to be fixed to the case (3), and a fixing part (13) for fixing the substrate (5) to the case (3) is provided at least at one of both ends of the substrate (5) in the width direction and betweenthe magnetic detection el
