MAGNETIC SHEET, AND COIL MODULE INCLUDING THE MAGNETIC SHEET, AND NON-CONTACT POWER SUPPLY DEVICE
To provide a magnetic sheet that can be stably manufactured and also has excellent magnetic characteristics, and a coil module which include the magnetic sheet and a non-contact power supply device.SOLUTION: A magnetic sheet 2 includes Mn-Zn based ferrite as a main component, and is composed of a sheet-like sintered body. In a cross section of the magnetic sheet 2, the absolute value of a difference |σs-σc| between a residual stress σs in a surface layer part and a residual stress σc in the center part is 20 MPa or less.SELECTED DRAWING: Figure 1
【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。【解決手段】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る磁性シート２である。この磁性シート２は、断面における表層部の残留応力σｓと中心部の残留応力σｃとの差｜σｓ−σｃ｜が、絶対値で、２０ＭＰａ以下である。【選択図】図１
