To provide an external wall of a sailing body capable of certainly adhering an elastic body layer and a fiber reinforced resin layer on each other so that air is not interposed and preventing attachment of underwater life and its manufacturing method.
The air is hardly interposed between the elastic body layer 10 and the epoxy resin layer 30 and the elastic body layer 10 and the epoxy resin layer 30 are favorably adhered on each other through a cloth material layer 20 as the cloth material layer 20 is integrated on the other surface in the thickness direction of the elastic body layer 10 and the epoxy resin layer 30 is formed on the other surface in the thickness direction of the elastic body layer 10 so as to cover the cloth material layer 20. Additionally, the air is hardly interposed between the epoxy resin layer 30 and the fiber reinforced resin layer 40, the fiber reinforced resin layer 40 is hardened without receiving influence of the elastic body layer 10 and the epoxy resin layer 30 and the fiber reinforced resin layer 40 are favorably adhered on each other as the fiber reinforced resin layer 40 is formed on a surface on the opposite side of the elastic body layer 10 on the epoxy resin layer 30.
