PROBLEM TO BE SOLVED: To provide the joining structure of a layered body in which a frequency selecting element used for a radome is incorporated, the radome being capable of preventing incidence or reflection of an electromagnetic wave from the joining part of the layered body and reducing the radar reflection cross-sectional area. SOLUTION: The radome 1 is configured with the layered body 7 of a sandwich structure wherein nonmetallic honey-comb layers 5a, 5b whose specific dielectric constant is lower than that of surface layers 4 are placed between the surface layers 4 made of a composite material and the frequency selecting element 6 configured with a copper clad resin film, a copper clad layer plate, or conductive ink or the like is interposed between the honey-comb layers 5a, 5b. When the radome 1 in which the frequency selecting element 6 is incorporated covers a radar antenna for assembling, a conductive joining member 9 such as a conductive adhesive is applied to a prescribed range X of a surface of the layered body 7 to cover the range in order to prevent the incidence or reflection of the electromagnetic wave from the joining part of the layered body 7 and reduce the radar reflection cross-sectional area.
