PROBLEM TO BE SOLVED: To provide a power transmission system, power transmission apparatus and power reception apparatus having a structure capable of keeping fluctuations in a coupling coefficient (κ) low in both cases where a power transmission coil and a power reception coil are in a facing state and in a positional deviation state.SOLUTION: The power transmission system includes a power reception coil 250 and a power transmission coil 450 wound so that a first power transmission winding section 450a and a second power reception winding section 250b do not overlap when the first power transmission winding section 450a and the first power reception winding section 250a overlap at a position where a power transmission winding axis CL1 and a power reception winding axis CL2 are displaced from each other in a plan view.SELECTED DRAWING: Figure 7

    【課題】送電コイルと受電コイルとが正対状態の場合、および、位置ずれ状態の場合のいずれであっても、結合係数(κ)の変動を小さく抑えることのできる構成を備える電力伝送システム、送電装置、および、受電装置を提供する。【解決手段】この電力伝送システムは、平面視において、送電巻回軸CL1と受電巻回軸CL2とがずれた位置において第1送電巻線部450aと第1受電巻線部250aとが重なる場合に、第1送電巻線部450aと第2受電巻線部250bとは重ならないように、受電コイル250および送電コイル450が巻回されている。【選択図】図7
