Abstract

A current sensor may include a first support portion and a first lead frame which is made of a material different from that of the first support portion. The current sensor may include: a signal processing IC which has a first surface supported by a first surface of the first support portion and is electrically connected to the first lead frame; at least one magnetoelectric conversion element which is configured separately from the signal processing IC, is mounted on a second surface on a side opposite to the first surface of the signal processing IC, and outputs, to the signal processing IC, a signal processed by the signal processing IC; and a second lead frame which has a second terminal portion, at least a part of which is arranged to face the second surface of the signal processing IC, and through which a measurement current flows.
