To provide a method for manufacturing an antenna plate in which rust and corrosion are hardly caused.
A method for manufacturing an antenna plate of the present invention is as follows. Prior to laminate a coating film 23 on a metal plate 21 having an antenna part 3, a spacer 6 larger than a feeding part 24 of the antenna part 3 is disposed at a place corresponding to the feeding part 24, and then, the coating film 23 is laminated on a surface of the metal plate 21. After this, cutting means 72 is inserted up to a midway point in the thickness direction of the spacer 6 from the coating film 23, thereby cutting the place corresponding to the feeding part 24 of the coating film 23, and then, the coating film 23 having been cut and the spacer 6 having been cut in up to the midway point are removed to expose the feeding part 24.
