CURRENT SENSOR

WIPO Patent Application WO/2018/092337

A1

This current sensor (100) is provided with: a conductor (110) provided with a first flow path part (110a) through which a portion of a current being measured flows, and a second flow path part (110b) through which the other portion of the current flows; a first magnetic element (120a) which detects the intensity of a first magnetic field generated by the current flowing through the first flow path part; a second magnetic element (120b) which detects the intensity of a second magnetic field generated by the current flowing through the second flow path part; a substrate (160) which holds the first magnetic element and the second magnetic element; and a lead frame (151) which is connected to the first magnetic element (120a), the second magnetic element (120b), and the substrate. The lead frame (151) is provided on the side of one main surface (161) of the substrate (160). The first magnetic element (120a) and the second magnetic element (120b) are provided between the first flow path part (110a) and the second flow path part (110b), and between the lead frame (151) and the one main surface (161) of the substrate (160).
