Claim Text:
1. A current sensor comprising: a mounting unit including a disposition region in which a current path is disposed, a current flowing through the current path in a first direction defining X-direction, the current path having a flat-plate shape having a width in Y-direction perpendicular to the X-direction; an only pair of magnetic detection elements consisting of a first magnetic detection element and a second magnetic detection element disposed on the mounting unit such that the disposition region is interposed therebetween; and an arithmetic circuit provided on the mounting unit, the arithmetic circuit being configured to perform an arithmetic operation on a value of the current flowing through the current path on the basis of detection values of the pair of magnetic detection elements, wherein the first and second magnetic detection elements are arranged on opposite sides of a virtual line passing through a gravity center of the current path, the virtual line extending in Z-direction perpendicular to the X-direction and the Y-direction, each of the first and second magnetic detection elements has a respective sensitivity axis parallel to the Y-direction.
