摘要： A current sensor includes: a magneto electric conversion element; and a magnetic field concentrating core applying a magnetic field caused by a measurement object current to the magneto electric conversion element. A planar shape of the magnetic field concentrating core perpendicular to a current flowing direction is a ring shape with a gap. The magneto electric conversion element is arranged in the gap. A part of a conductor for flowing the current is surrounded by the magnetic field concentrating core. The magnetic field concentrating core includes two first magnetic members and at least one second magnetic member, which are stacked alternately in the current flowing direction. Parts of the two first magnetic members adjacent to each other via the one second magnetic member are opposed to each other through a clearance or an insulator.

摘要： 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.
