<p><P>PROBLEM TO BE SOLVED: To provide a non-contact feed device in which a secondary coil and a core member of a power receiving module are arranged in a limited space with balance to transfer power efficiently, to provide the power receiving module used in the non-contact feed device, and to provide a portable electronic apparatus including the power receiving module. <P>SOLUTION: A magnetic core 24 is arranged on a secondary coil 23 surface opposite to a surface facing a primary coil. The power receiving module 21 is so structured that, when a direction perpendicular to the secondary coil 23 surface facing the primary coil is defined as a height direction, and a height of the secondary coil 23 is denoted by h1 and a height of the magnetic core 24 is denoted by h2, a ratio (h1/h2) of the height h1 of the secondary coil 23 to the height h2 of the magnetic core 24 satisfies a relationship of h1/h2>1.2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
