Abstract
(EN)
The problem addressed by the present invention is to provide a technology for enhancing the accuracy of the high-frequency current detection of a current detection device. A current detection device according to the present invention is characterized in that at least two conductors are provided through which current split from the same conductor flows, the conductors through which the split current flows have parts that oppose each other, current flows in reverse directions through the opposing parts of the conductors, and a magnetic field detection element is provided between the opposing parts of the conductors.
