Abstract
A current detection system includes: first and second magnetic plates arranged in parallel with a predetermined distance; a bus bar for flowing current; and a magneto-electric conversion element converting a lateral direction component of a measurement object magnetic flux, generated by current flowing through the bus bar, to an electric signal. When an external magnetic flux in a lateral direction passes through an accommodation space between the first and second magnetic plates, a trajectory of the external magnetic flux is bent by the first and second magnetic plates, and the accommodation space is divided into a permeable space, through which the external magnetic flux passes, and a non-permeable space, through which the external magnetic flux does not pass. The bus bar is arranged in the accommodation space. The magneto-electric conversion element is arranged in the non-permeable space. The bus bar and the magneto-electric conversion element are lined in the height direction.
