MAGNETIC SHEET, COIL MODULE INCLUDING MAGNETIC SHEET, AND NON-CONTACT POWER SUPPLY DEVICE
To provide a magnetic sheet that can be stably manufactured and has excellent magnetic properties, and a coil module and a non-contact power supply device having the magnetic sheet.SOLUTION: A magnetic sheet 2 according to the present invention contains Mn-Zn ferrite as a main component and is composed of a sheet-shaped sintered body. In the thickness direction of the cross section of the magnetic sheet 2, when the maximum value of the Zn content converted into oxides is ZMAX, and the minimum value of the Zn content converted into oxides is ZMin, the ratio of ZMin to ZMAX (ZMin/ZMAX×100) is 90% or more.SELECTED DRAWING: Figure 2
【課題】安定して製造が可能であって、かつ、優れた磁気特性を有する磁性シートと、当該磁性シートを有するコイルモジュールおよび非接触給電装置とを提供すること。【解決手段】本発明の磁性シート２は、主成分としてＭｎ－Ｚｎ系フェライトを含み、シート状の焼結体で構成されている。そして、磁性シート２の断面の厚み方向において、酸化物換算したＺｎ含有量の最大値をＺMAXとし、酸化物換算したＺｎ含有量の最小値をＺMinとすると、ＺMAXに対するＺMinの比率（ＺMin／ＺMAX×１００）が、９０％以上である。【選択図】図２
