To provide a power transmitter and a power receiver which can be downsized while improving power supply efficiency.SOLUTION: In a non-contact power supply system 10 that supplies power in a non-contact manner between a power transmitter 20 provided on a road side and a power receiver provided on the vehicle side, the power receiver includes three-phase resonance coils on the reception side 31Lu, 31Lv and 31Lw, a ferrite core bonding a magnetic flux, and resonance capacitors on the reception side 31Cu, 31Cv and 31Cw. The resonance coils on the reception side 31Lu, 31Lv and 31Lw are arranged so that at least one distance between coils is different from other distance between coils among the distances between the coils. According to the distance between the coils, the capacitor capacities of the resonance capacitors on the reception side 31Cu, 31Cv and 31Cw are set.SELECTED DRAWING: Figure 1

    【課題】給電効率を向上させつつ、小型化することができる送電装置及び受電装置を提供する。【解決手段】道路側に設けられる送電装置20と車両側に設けられる受電装置との間で、非接触で給電を行う非接触給電システム10において、受電装置は、3相の受電側共振コイル31Lu、31Lv、31Lwと、磁束を結合させるフェライトコアと、受電側共振コンデンサ31Cu、31Cv、31Cwと、を備える。受電側共振コイル31Lu、31Lv、31Lwは、そのコイル間距離のうち、少なくとも1のコイル間距離が他のコイル間距離と異なるように配置されている。コイル間距離に応じて、受電側共振コンデンサ31Cu、31Cv、31Cwのコンデンサ容量が設定されている。【選択図】図1
