The purpose of the present invention is to provide a current sensor exhibiting excellent insulation resistance. This current sensor (1) is provided with: a conductor (10); a support part (30) for supporting a signal processing IC (20); a magnetoelectric conversion element (13) which is configured so as to be capable of electrically connecting with the signal processing IC (20), and which is disposed in a gap (10a) in the conductor (10) so as to detect a magnetic field generated from current flowing in the conductor (10); and an insulation member (14) for supporting the magnetoelectric conversion element (13).
