This non-contact power supply device is provided with a second coil which contactlessly transmits power to or receives power from a first coil at least by means of magnetic coupling, multiple sensors for detecting position shifts between the first coil and the second coil, a position detection means which, on the basis of the output values of the sensors, detects the relative positions of the first coil and the second coil, and a foreign object detection means which compares the output values of the sensors and from these comparison results detects foreign objects between first coil and the second coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-contact power supply device","description":"Provided is a non-contact power supply device which detects foreign objects interposed between a power transmission coil and a power receiving coil.
