Abstract

A current sensor includes a folded-shaped current path including a pair of arm portions extending in parallel with each other, and a pair of magnetoelectric conversion elements provided so as to sandwich therebetween a symmetric axis passing between the pair of arm portions, the pair of magnetoelectric conversion elements being used for detecting magnetism caused by a current passing through the pair of arm portions, wherein a half-bridge circuit in which the pair of magnetoelectric conversion elements is series-connected and a signal is able to be extracted from a connection point between the pair of magnetoelectric conversion elements is formed, and sensitivity axes of the pair of magnetoelectric conversion elements are oriented in a same direction and sensitivity-influencing axes of the pair of magnetoelectric conversion elements are oriented in a same direction.
