POWER TRANSMITTING DEVICE, POWER RECEIVING DEVICE, AND POWER TRANSMISSION SYSTEM

摘要

A power transmitting device (41) which is used in a power transmission system using electromagnetic field resonance. This power transmitting device (41) comprises a power transmission-side electromagnetic induction coil (23), a power transmission-side resonance part (28), and a power transmission-side shield part (51) that surrounds the power transmission-side electromagnetic induction coil (23) and the power transmission-side resonance part (28). The power transmission-side electromagnetic induction coil (23) and the power transmission-side resonance part (28) are arranged in the same plane.
