To provide power transmission for reducing a radiation loss of electromagnetic waves as much as possible and efficiently achieving long-distance power transmission, and to provide a method of manufacturing the same.

Power is transmitted through the inside of an iron tube, a ceramic tube, or a glass tube (for short, glass tube) for efficiently transmitting power, or the inside of a glass tube where the outside is subjected to vapor deposition or plating by a noble metal, such as gold, silver, and copper by using single-wavelength sinusoidal electromagnetic waves having straight-advancing performance and directivity.
