Abstract
The present invention is mainly directed to providing a wireless power relay device and a wireless power transmission device, which are capable of arranging a relay coil having higher transmission efficiency in a transmission-efficiency reducing section having lower transmission efficiency than those of a plurality of relay coils, thereby preventing power transmission efficiency from sharply decreasing in the transmission-efficiency reducing section.
