To provide an antenna power feed apparatus constituting an antenna on a place of good visibility even when an antenna can not be installed owing to an installation space or beauty.
An escape guide lamp 10 is provided with a guide display board 12 formed on an opening surface of a metallic frame body 11. An insulating gap 15 is formed at a center section of the upper surface of the metallic frame body 11 to divide the upper surface into two right and left sections, and a power feed box 16 is attached to the place on which the insulating gap 15 is formed. The power feed box 16 is constituted so that a metallic casing 17 of which the lower side is opened is arranged on an insulating casing 18 and an input/output plug 21 is attached to the metallic casing 17. The input/output plug 21 is constituted so that a center conductor 23 is connected to one side part of the insulating gap 15 by a feed fitting 25 and a feed bolt 26, an outer conductor 22 is connected to the other side part of the insulating gap 15 by the metallic casing 17, an earth fitting 20 and an earth bolt 27, and the metallic frame body 11 of the escape guide lamp 10, on which the insulating gap 15 is formed, is driven as an antenna.
