Abstract
A current sensor structure includes a substantially ring-shaped magnetic core comprising layers of magnetic plates to be accommodated in an insulating case and secured to the case via a molding compound. Projections protruding in the magnetic plate's thickness direction are provided either on a front-side wall portion of the case in the thickness direction or on a surface of the magnetic core in the thickness direction. By virtue of, the surface of the magnetic core is supported by the front-side wall portion via the projections, leaving a gap between this surface and the wall portion to the same height as that of the projections. The gap is filled with the molding compound. Dilative and contractive deformation of the case in the direction orthogonal to the thickness direction is absorbed by the molding compound in the gap to prevent the stress from acting upon the magnetic core.
