To improve the quality of a radome which uses a cyanate ester resin for a skin layer.SOLUTION: A radome 10 is formed by a multilayer body, in which a plurality of skin layers is laminated on a surface of a core material 12. The plurality of skin layers includes a first fiber-reinforced plastic layer 20, which contains a cyanate ester resin and a fiber material, and a second fiber-reinforced plastic layer 16, which contains an epoxy resin and a fiber material. The second fiber-reinforced plastic layer 16 is arranged in a position where the skin layer is in contact with the surface of the core material 12. It is preferable that the proportion of the thickness of the second fiber-reinforced plastic layer 16 in the total thickness of the skin layer is 50% or less.SELECTED DRAWING: Figure 2 【課題】シアネートエステル樹脂をスキン層に用いたレドームの品質を向上する。【解決手段】レドーム１０は、コア材１２の表面に複数のスキン層を積層した積層体で形成されている。複数のスキン層は、シアネートエステル樹脂と繊維素材とを含有する第１の繊維強化プラスチック層２０と、エポキシ樹脂と繊維素材とを含有する第２の繊維強化プラスチック層１６とを備え、コア材１２の表面と接する位置には、第２の繊維強化プラスチック層１６が配置されている。第２の繊維強化プラスチック層１６の厚さがスキン層全体の厚さに占める割合は５０％以下であることが好ましい。【選択図】図２
