PROBLEM TO BE SOLVED: To suppress leakage of an electromagnetic wave in power transmission.SOLUTION: An electromagnetic leakage prevention device comprises a metallic tube, an opening, and a magnetic substance unit. The metallic tube is formed so as to surround a circumference of a first power transmission device for performing radio power transmission using an electromagnetic wave with another power transmission device arranged opposingly. The opening is formed in the metallic tube along the circumference direction of the metallic tube. The magnetic substance unit is arranged inside of the metallic tube along the circumference direction of the metallic tube. |
