CURRENT MEASUREMENT DEVICE

摘要

Disclosed is a current measurement device that can highly accurately measure the magnitude of current in a predetermined conductor even if there is a plurality of conductors. The current measurement device that measures the magnitude of current has a plurality of conductors aligned on the surface of a substrate and has a magnetic sensor that measures the magnetic field generated when measured current flows through the conductors; the magnetic sensor has a selective level of sensitivity to magnetic fields with respect to a direction parallel to the surface of the substrate and is provided, in a plan view, superimposed above or below the measured conductor that the magnetic sensor measures out of the plurality of conductors; and the other conductors among the plurality of conductors are provided at positions such that that directions of the magnetic fields generated by the other conductors are in directions that the magnetic sensor is not sensitive to.
