POWER RECEIVING DEVICE, ELECTRONIC APPARATUS USING SAME AND NON-CONTACT CHARGER

摘要

Disclosed is an electronic apparatus (1) comprising a power receiving device (2) and an electronic apparatus main body (3). The power receiving device (2) comprises a power receiving coil (11) having a spiral coil, a rectifier (12) and a secondary battery (13). The electronic apparatus main body (3) comprises an electronic device (14) and a circuit board (15). A magnetic foil body (16) is arranged in at least one position between the spiral coil (11) and the secondary battery (13), the rectifier (12), the electronic device (14) or the circuit board (15). The magnetic foil body (16) has a value expressed as the product of the real component of relative magnetic permeability µr' and the thickness t, namely µr'·t, of not less than 30,000.
