MAGNETIC SHEET, COIL MODULE HAVING MAGNETIC SHEET, AND NON-CONTACT POWER SUPPLY DEVICE
A magnetic sheet according to the present invention contains Mn—Zn ferrite as a main component and is comprised of a sheet-shaped sintered body. Besides, a ratio of ZMIN to ZMAX (ZMIN/ZMAX×100) is 90% or more, in which a maximum value of a content of Zn in terms of oxide is set to ZMAX and a minimum value of the content of Zn in terms of oxide is set to ZMIN in a thickness direction of a cross section of the sintered body.
