MAGNETIC SHEET FOR NON-CONTACT POWER RECEIVING DEVICE, NON-CONTACT POWER RECEIVING DEVICE, ELECTRONIC APPARATUS, AND NON-CONTACT CHARGER

摘要

A magnetic sheet of an embodiment includes a laminate of a plurality of magnetic thin plates. The laminate constituting the magnetic sheet includes a first magnetic thin plate and a second magnetic thin plate different in kind from the first magnetic thin plate. The first magnetic thin plate has a magnetostriction constant exceeding 5 ppm in an absolute value, and the second magnetic thin plate has a magnetostriction constant of 5 ppm or less in an absolute value. Alternatively, the first magnetic thin plate has a thickness of from 50 to 300 μm, and the second magnetic thin plate has a thickness of from 10 to 30 μm.
