<p><P>PROBLEM TO BE SOLVED: To provide a cut core in which a chamfer is formed on the edge of a cut surface, having a structure effective for suppressing the conduction between thin strips. <P>SOLUTION: A cut core formed by cutting off a wound metal thin strip, includes a chamfer part formed in at least one side perpendicular to a lamination direction of the metal thin strips, of four sides of a cut surface having a rectangle shape. A portion removed from the cut core by formation of the chamfer part is larger in dimension in a direction perpendicular to the cut surface than in the lamination direction. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
