A radio wave transmissive cover includes a cover body having a transparent first cover layer, a colored second cover layer, and a base material layer. The second cover layer is formed on the back surface of the first cover layer. The base material layer is formed on the back surface of the second cover layer. An opening is provided between the outer circumference and the center of the cover body. The opening extends through at least the base material layer and the second cover layer in the thickness direction, and the opening is open on the back surface of the base material layer. The base material layer and the second cover layer are joined together through a recess-protrusion relationship, thereby forming a sealing portion around the opening. The sealing portion seals the gap between the base material layer and the second cover layer.
