CAPTEUR DE COURANT DE BASSE DEPENDANCE SUR LA FREQUENCE AVEC ELEMENT DE CONVERSION MAGNETO-ELECTRIQUE

摘要

[Object] A purpose is to provide a current sensor capable of accurately measuring a current to be measured even if the frequency of the current to be measured changes. [Solution] A current sensor 101 includes a first current path 12 including a first flat-shaped portion 12f, and a first magnetoelectric conversion element 13 arranged on the first current path 12 and configured to detect magnetism generated when a current to be measured flows through the first current path 12, wherein the current sensor 101 measures the current to be measured of a device to which the first current path 12 is connected, a first conductive convex portion 12w is provided, in the first current path 12, in a direction in which the current to be measured flows, and the first magnetoelectric conversion element 13 is arranged at a position on the first current path 12, at which a minimum frequency magnetic flux density serving as a magnetic flux density in a case of passing the current to be measured of a minimum frequency used in the device and a maximum frequency magnetic flux density serving as a magnetic flux density in a case of passing the current to be measured of a maximum frequency used in the device substantially coincide with each other.
