PURPOSE:To easily manufacture the waveguide without limitation of a curing temperature of a fiber reinforced plastic by employing a male die core member made of copper, forming a forming layer made of a fiber reinforced plastic on a metallic layer and melting and removing the male die core member. CONSTITUTION:A gold plating layer 1 is formed to a part on an outer face of a male die core member 5 made of copper except the part not coated with a plating mask 6, a nickel plating layer 2 and a copper plating layer 3 are sequentially formed. The plating layers are formed on the surface of the male die core member 5, a fiber reinforced plastic(FRP) layer is laminated on the plating layer, the FRP is cured by heating to form an FRP forming layer 4. Then the male die core member 5 is molten and removed entirely by using water solution of ferric chloride. Thus, the waveguide is realized in which the inner face and a flange face 7 for the connection to another waveguide are formed by the gold plating layer 1. |
