To improve quality of a radome using a cyanate ester resin for a skin layer. A radome is formed of a multilayer structure in which a plurality of skin layers are layered on a surface of a core member. The plurality of skin layers include a first fiber reinforced plastic layer containing the cyanate ester resin and a fiber material and a second fiber reinforced plastic layer containing an epoxy resin and a fiber material. The second fiber reinforced plastic layer is disposed at a position in contact with the surface of the core member. A proportion of a thickness of the second fiber reinforced plastic layer to a thickness of all of the skin layers is preferably 50% or less.
