Abstract

The manufacturing device is provided with a first roller and a second roller for molding an uneven-thickness film. The first roller is provided with a truncated-cone-shaped portion and a disc-shaped portion, the diameter of the disc-shaped portion is larger than the diameter of a large-diameter face of the truncated-cone-shaped portion, and the second roller is provided with a column-shaped portion. A thick part is formed in a molded body of the uneven-thickness film between the truncated-cone-shaped portion of the first roller and the column-shaped portion of the second roller, and a thin connecting part is formed in the molded body between the disc-shaped portion of the first roller and the column-shaped portion of the second roller.
