The power transmission device includes switching elements that make a power-transmission resonant circuit generate an alternating magnetic flux from a power source circuit. The power reception device includes a magnetism collecting device having a magnetism collecting circuit not connected to a load, a power receiving coil which is capable of being magnetically coupled to the magnetism collecting device, and a rectifier circuit that supplies output power of the power receiving coil to a load. A power-transmission resonance frequency of the power-transmission resonant circuit is smaller than a drive frequency of each of switching elements, and a power-reception resonance frequency of the magnetism collecting circuit is larger than the drive frequency of each of switching elements. Accordingly, the present invention provides a noncontact power supply device with high power transmission efficiency and with excellent productivity."},"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":"A noncontact power supply device includes a power transmission device, a magnetism collecting device, and a power reception device.
