<p><P>PROBLEM TO BE SOLVED: To provide a magnetic sheet that is disposed between a power receiving coil and a secondary battery in a non-contact charging system, and can achieve simultaneously an improvement in transmission efficiency and a reduction in an eddy current loss by considering a fine structure of Fe-based nanocrystal alloy thin plate, and also does not cause a scattering of metal powder and contamination. <P>SOLUTION: The magnetic sheet is characterized in that the sheet has the Fe-based nanocrystal alloy thin plate in which both sides are interposed between organic films through an adhesive layer and fine cracks are formed therein. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
