PROBLEM TO BE SOLVED: To provide a non-contact power transmission device and a non-contact power reception device which include cooling devices and yet inhibit enlargement of the devices.SOLUTION: A non-contact power transmission device includes: a power transmission part 24 which transmits power to a power reception device in a non-contact manner; and a cooling device 25 which cools the power transmission part 24. The power transmission part 24 includes a power transmission core 30 and a power transmission coil provided at the power transmission core 30. The cooling device 25 includes: a stator 41 including a stator core provided at the power transmission core 30 and a stator coil provided at the stator core 41; a rotor 42 which is provided spaced away from the stator 41 so as to rotate relative to the stator 41; and cooling fins provided at the rotor 42. A magnetic flux path of magnetic flux from the stator coil passes through the stator core and the power transmission core 30.SELECTED DRAWING: Figure 3

    【課題】冷却装置を備える一方で、装置の大型化が抑制された非接触送電装置および非接触受電装置を提供する。【解決手段】非接触送電装置は、受電装置に非接触で送電する送電部24と、送電部24を冷却する冷却装置25とを備え、送電部24は、送電コア30と、送電コア30に設けられた送電コイルとを含み、冷却装置25は、送電コア30に設けられた固定子コアおよび固定子41コアに設けられた固定子コイルを含む固定子41と、固定子41から間隔をあけて設けられると共に固定子41に対して回転するように設けられた回転子42と、回転子42に設けられた冷却フィンとを含み、固定子コイルからの磁束の磁束経路は、固定子コアと送電コア30とを通る。【選択図】図3
