A current sensor includes magneto-electric conversion elements divided into a first and second group. The first and second groups are positioned so as to interpose a cut formed in a printed circuit board between them. The first and second groups are symmetrically positioned with respect to a first virtual line. The magneto-electric conversion elements in the first and second groups are symmetrically positioned with respect to a second virtual line orthogonal to the first virtual line at a positioning position at which a to-be-measured current path is positioned. The sensitivity axes of each of pairs of magneto-electric conversion elements that are symmetrical with respect to the positioning position are oriented in parallel in the same direction or opposite directions. An inter-element spacing between adjacent magneto-electric conversion elements in the first and second groups is narrower than an inter-group spacing, which is the narrowest spacing between the first and second groups.
