<p>Provided is a downsized and inexpensive power distribution information measuring device capable of measuring power distribution information such as current, power, and so forth in an electrical path to be measured with a high degree of accuracy. The power distribution information measuring device is provided with a magnetic field sensor (10) and a holding unit (first case unit (20), second case unit (30)) for holding said magnetic field sensor so as to surround a first conductor constituting an electrical path (40) as a subject to be measured, and the holding unit is configured to hold the magnetic field sensor (10) at the electrical path such that the detection direction (Ds) of the magnetic field sensor (10) is in line with the direction orthogonal to the line segment connecting the center of the cross-sectional area of the electrical path and the center of said magnetic field sensor, and the distance between the center (Oc) of said electrical path and the center (Os) of said magnetic sensor (10) stays constant.</p> |
