The Pq radome is constructed as described above and manufactured as follows. First, a mold release agent (9) is provided in a molding die (7). Then, apply molten ceramic mist (61) to a predetermined thickness in a blowing gun (81) on the surface of the molding die (7) provided with this mold release agent (9), cool and solidify it. Semi-hardened FRP board (4), honeycomb core (3)
1 and the semi-hardened FRP plate (4) are sequentially placed on the solidified ceramic mist (6) layer and heated and press-molded. At this time, the surface opposite to the entire solidified layer of the solidified ceramic mist (61) is a rough surface, but the resin impregnated into the FRP & (4) during molding spreads over the rough surface and forms the solidified layer of the ceramic mist (6). The FRP plate (4) is frequently bonded.Also, even if there are pores penetrating through the solidified ceramic mist (61), the FRP plate (4) will not contain any anti-reflection during molding. The resulting working fat reaches these pores, pierces them, and hardens them. When the molding is completed and the mold is removed from the molding die (7), a radome with ceramic applied to the outer surface is manufactured.
