Document Type and Number:
WIPO Patent Application WO/2012/098851
Kind Code:
A1
Abstract:
To provide a resonance-coil holding device, and a resonance coil unit, and a non-contact type electric power transmission apparatus, which can prevent surface discharge in low cost without increasing a size of a resonance coil, a coil bobbin of a resonance coil unit is provide with helical even surface portions fixing a plurality of single-turn wire portions of the resonance coil at intervals to each other, and a helical projecting ridge arranged between the helical even surface portions. The helical projecting portion is configured to have a surface distance between adjacent single-turn wire portions of a resonance coil fixed by the helical even surface portions with a length corresponding to voltage difference which is generated between each of the adjacent single-turn wire portions.
