Claim:
1. A current sensor comprising: a U-shaped current path including a pair of arm portions extending in parallel to each other, the current path having a symmetry axis thereof extending between the pair of arm portions; a first pair of magnetoelectric conversion elements provided so as to sandwich the symmetry axis therebetween, the pair of magnetoelectric conversion elements being configured to detect magnetism caused by a current passing through the pair of arm portions, the first pair of magnetoelectric conversion elements being connected in series to form a first half-bridge circuit such that a signal is extracted from a connection point of the pair of magnetoelectric conversion elements; and a second pair of magnetoelectric conversion elements which form a second half-bridge circuit, wherein the first and second half-bridge circuits are connected in parallel to form a full-bridge circuit, wherein the first pair of magnetoelectric conversion elements have respective sensitivity axes oriented in a same first direction, and respective sensitivity-influencing axes oriented in a same second direction, and wherein the second pair of magnetoelectric conversion elements have respective sensitivity axes oriented in a direction opposite to the first direction.
