<p>PROBLEM TO BE SOLVED: To provide a current sensor that can maintain high current measurement accuracy even if an electric wire flowing a measured current is bent.SOLUTION: The current sensor comprises: a substrate (11) that has an insertion hole (11b) to which a first part of an electric wire (15) provided with a first part (15a) and a second part (15b) having an angle with respect to the first part (15a) is inserted; and a plurality of magnetoelectric conversion elements (12) that is arranged in the substrate so as to surround the insertion hole. The plurality of magnetoelectric conversion elements is arranged at equal intervals so as to be along a circle (C1) having the first part to be inserted to the insertion hole overlapped with a center (O1), and is arranged so that a direction indicated by an angle (θ1a) of a quarter of a an angle (θ1b) formed with two linear lines (L1a and L1b) connecting each of any two adjacent magnetoelectric conversion elements (12a and 12b) to the first part in an in-plane including the circle is made parallel with the second part.</p> |
