Abstract: A wireless power transmission system that transmits alternating-current power includes a power-transmitting device including first and second electrodes spaced apart and having a total width of λ/2π or less, i.e., a near field range, and a first inductor between the first and second electrodes and a AC power-generating section, and a power-receiving device including third and fourth electrodes spaced apart and having a total width of λ/2π or less, and a second inductor between the third and fourth electrodes and a load. A coupler including the first and second electrodes and the first inductor forms one resonant circuit and a coupler including the third and fourth electrodes and the second inductor forms another resonant circuit. Resonance frequencies of the couplers are substantially equal. The first and second electrodes and the third and fourth electrodes are spaced apart by λ/2π or less.

Abstract: The insulation covered conductive wire includes a conductive wire, a non-adherent, laterally wound insulation member and a non-adherent braided insulation member. The non-adherent, laterally wound insulation member covers an outer circumference of the conductive wire without adhering thereto and is formed by laterally winding a plurality of first ceramic fibers constituted from a plurality of first ceramic strands in an extending direction of the conductive wire. The first ceramic strands are not in contact with each other and do not adhere to each other. The non-adherent braided insulation member covers an outer circumference of the non-adherent, laterally wound insulation member without adhering thereto and is formed by braiding a plurality of second ceramic fibers constituted from a plurality of second ceramic strands. The second ceramic fibers are not in contact with each other and do not adhere to each other.
