COIL UNIT AND POWER SUPPLYING SYSTEM
First Claim
1. A coil unit used for a power supplying system that, when a pair of coils is separately disposed in a direction perpendicular to an axial direction of the coils, contactlessly supplies power from one coil to the other coil, the coil unit comprising:
- a flat panel-like core; and
the coils wound around the core,wherein the core is divided into a plurality of portions along the axial direction of the coils, andwherein the core is divided such that a width of both end portions is shorter than a width of the center portion.

Abstract
A power supplying system magnetically resonates between a primary resonant coil that configures a primary core unit and a secondary resonant coil that configures a secondary core unit for contactlessly supplying the power. The primary and secondary resonant coils are wound around the primary and secondary ferrite cores respectively, and face each other in the direction perpendicular to the axial direction of the primary and secondary resonant coils when supplying the power. The primary and secondary ferrite cores are divided into a plurality of portions along the axial direction of the primary and secondary resonant coils such that a width of the both end portions is shorter than a width of the center portion.
