NON-CONTACT CHARGING MODULE, NON-CONTACT CHARGER USING THE SAME AND PORTABLE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a small size non-contact charging module, a non-contact charger using the same and a portable terminal capable of being suitably used irrespective of use of a magnet included in the other party's non-contact charging module transmitting the power by eliminating alteration of L-value of a coil provided in the non-contact charging module when positioning a primary non-contact charging module with a secondary non-contact charging module.

SOLUTION: The non-contact charging module includes: a planar coil 2c in which a conductor is wound in a generally oval shape; and a magnetic sheet 52 including a plane for placing the planar coil 2c. A void portion of a generally oval shape of the planar coil 2c has a shorter width smaller than the diameter of a circular magnet 30a and a longer width larger than the diameter of the circular magnet 30a.
