Abstract
A current measurement device includes: four or more triaxial magnetic sensors arranged to have predefined positional relationships such that magnetism-sensing directions thereof are parallel to each other; and a calculator configured to calculate currents flowing through a pair of conductors to be measured, which are arranged in proximity to each other, based on detection results of the four or more triaxial magnetic sensors and the positional relationships between the four or more triaxial magnetic sensors, the currents flowing in mutually opposite directions.
