Abstract
A pair of clamping parts clamp a conductor to be measured and biased in closing directions. A pair of gripping parts are provided to be able to change a distance between the respective clamping parts according to a distance therebetween. Magnetoelectric conversion element(s) for current measurement is/are provided on either one or both of the respective clamping parts. A distance measurement unit is provided to be able to measure a physical quantity corresponding to the distance between the respective gripping parts as a physical quantity corresponding to the distance between the respective clamping parts. A current calculation device is provided to obtain a current flowing in the conductor to be measured on the basis of a magnetic field detected by the magnetoelectric conversion element(s) for current measurement and the physical quantity measured by the distance measurement unit when the conductor to be measured is clamped by the respective clamping parts.
